Bringing powerful 3D X-ray microscopy to smaller labs

Researchers at the University of Michigan have developed a technique that allows the study of microstructures inside metals, ceramics, and rocks using X-rays in a standard laboratory, eliminating the need to travel to a particle accelerator. This advancement makes 3D X-ray diffraction (3DXRD) more accessible, enabling rapid analysis of samples and prototypes in both academic and industrial settings, and providing more opportunities for student involvement. 3DXRD works by reconstructing 3D images from X-rays taken at multiple angles, similar to a CT scan, but with the material sample rotating in front of a powerful beam that emits about a million times more X-rays than a medical X-ray.

The huge X-ray concentration produces a micro-scale image of the tiny fused crystals that make up most metals, ceramics and rocks, known as polycrystalline materials.

Results help researchers understand how materials react to mechanical stresses by measuring thousands of individual crystals’ volume, position, orientation and strain. For example, imaging a sample from a steel beam under compression can show how crystals respond to bearing the weight of a building, helping researchers understand large-scale wear.

Synchrotrons were once the only facilities able to produce enough X-rays for 3DXRD as electrons spit off scads of X-rays as they travel through circular particle accelerators, which can then be directed into a sample.

While synchrotron X-ray beams produce state-of-the-art detail, there are only about 70 facilities worldwide. Research teams must put together project proposals for “beam time.” Accepted projects often must wait six months to up to two years to run their experiments, which are limited to a maximum of six days.

In an effort to make this technique more widely available, the research team worked with PROTO Manufacturing to custom build the first laboratory-scale 3DXRD. As a whole, the instrument is about the size of a residential bathroom, but could be scaled down to the size of a broom closet.

“This technique gives us such interesting data that I wanted to create the opportunity to try new things that are high risk, high reward and allow teachable moments for students without the wait-time and pressure of synchrotron beam time,” said Ashley Bucsek, U-M assistant professor of mechanical engineering and materials science and engineering and co-corresponding author of the study published in Nature Communications.

Previously, small-scale devices could not produce enough X-rays for 3DXRD because at a certain point, the electron beam pumps so much power into the anode—the solid metal surface that the electrons strike to make X-rays—that it would melt. Lab-3DXRD leverages a liquid-metal-jet anode that is already liquid at room temperature, allowing it to take in more power and produce more X-rays than once possible at this scale.

The researchers put the design to the test by scanning the same titanium alloy sample using three methods: lab-3DXRD, synchrotron-3DXRD and laboratory diffraction contrast tomography or LabDCT—a technique used to map out crystal structures in 3D without strain information.

Lab-3DXRD was highly accurate, with 96% of the crystals it picked up overlapping with the other two methods. It did particularly well with larger crystals over 60 micrometers, but missed some of the smaller crystals. The researchers note that adding a more sensitive photon-counting detector, which detects the X-rays that are used to build the images, could help catch the finest-grained crystals.

With this technique available in-house, Bucsek’s research team can try new experiments, honing parameters to prepare for a larger experiment at a synchrotron.

“Lab-3DXRD is like a nice backyard telescope while synchrotron-3DXRD is the Hubble Telescope. There are still certain situations where you need the Hubble, but we are now well prepared for those big experiments because we can try everything out beforehand,” Bucsek said.

Beyond enabling more accessible experiments, lab-3DXRD allows researchers to extend projects past the synchrotron six day limit, which is particularly helpful when studying cyclic loading—how a material responds to repeated stresses over thousands of cycles.

One minute Mentor: Tool Steels Heat Treatment Simulation Example

The potential of high-temperature simulation (HTS) is demonstrated through the case of a low-silicon, vacuum-arc-melted and remelted H11 hot-work tool steel. To validate the HTS model, a cylindrical steel sample with a diameter and length of 100 mm (4 inches) was selected due to the efficiency benefits of using a simplified 2D geometry. The simulation was calibrated using time-temperature-transformation (TTT) diagrams and thermal expansion data obtained from dilatometer experiments. Initial validation focused on comparing simulated phase-transformation behavior with actual dilatometer curves, showing good agreement in key areas such as thermal expansion, austenite formation (with carbides), subsequent contraction, and the transformation kinetics of austenite into martensite, bainite, and pearlite. The model does not currently account for the precipitation of proeutectoid carbides.

New material gives copper superalloy-like strength

Researchers from the U.S. Army Research Laboratory and Lehigh University have developed a nanostructured copper alloy (Cu-Ta-Li) with exceptional thermal stability and mechanical strength, potentially redefining high-temperature materials for aerospace, defense, and industrial applications. This groundbreaking alloy is one of the most resilient copper-based materials ever created. The research, supported by a $25 million cooperative agreement and Lehigh’s Presidential Nano-Human Interfaces Initiative, highlights the decade-long partnership between Lehigh and ARL in advancing materials science.

“This is cutting-edge science, developing a new material that uniquely combines copper’s excellent conductivity with strength and durability on the scale of nickel-based superalloys,” said Martin Harmer, the Alcoa Foundation Professor Emeritus of Materials Science and Engineering at Lehigh and a co-author of the study. “It provides industry and the military with the foundation to create new materials for hypersonics and high performance turbine engines.”

The ARL and Lehigh researchers collaborated with scientists from Arizona State University and Louisiana State University to develop the alloy, which can withstand extreme heat without significant degradation.

This and other innovative alloys will continue to be studied in Lehigh’s newly outfitted high-tech research labs, the Nanoalloy Lab and Nanoceramics Lab, which include high-pressure torsion systems, nanoindentation equipment and specialized high-temperature furnaces.

The breakthrough comes from the formation of Cu₃Li precipitates, stabilized by a Ta-rich atomic bilayer complexion, a concept pioneered by the Lehigh researchers. Unlike typical grain boundaries that migrate over time at high temperatures, this complexion acts as a structural stabilizer, maintaining the nanocrystalline structure, preventing grain growth and dramatically improving high-temperature performance.

The alloy holds its shape under extreme, long-term thermal exposure and mechanical stress, resisting deformation even near its melting point, noted Patrick Cantwell, a research scientist at Lehigh University and co-author of the study.

By merging the high-temperature resilience of nickel-based superalloys with copper — which is known for exceptional conductivity — the material paves the way for next-generation applications, including heat exchangers, advanced propulsion systems and thermal management solutions for cutting-edge missile and hypersonic technologies.

This new Cu-Ta-Li alloy offers a balance of properties not found in existing materials:

  • Nickel-based superalloys (used in jet engines) are extremely strong but lack the high thermal conductivity of copper alloys.
  • Tungsten-based alloys are highly heat-resistant but dense and difficult to manufacture.
  • This Cu-Ta-Li alloy combines copper’s exceptional heat and electrical conductivity while remaining strong and stable at extreme temperatures.
  • While not a direct replacement for traditional superalloys in ultra-high temperature applications, it has the potential to complement them in next-generation engineering solutions.

The team synthesized the alloy using powder metallurgy and high-energy cryogenic milling, ensuring a fine-scale nanostructure. They then subjected it to:

  • 10,000 hours (over a year) of annealing at 800°C, testing its long-term stability.
  • Advanced microscopy techniques, revealing the Cu₃Li precipitate structure.
  • Creep resistance experiments, confirming its durability under extreme conditions.
  • Computational modeling using density functional theory (DFT), which validated the stabilizing role of the Ta bilayer complexion.

A project such as this takes years of careful work and collaboration, said Christopher Marvel ’12 ’16 Ph.D., an author of the paper and professor of mechanical engineering at Louisiana State University.

“Lehigh has such a strong reputation for electron microscopy, and that is what interested the ARL in working with us on this material. It was our microscopy that was really key to understanding the material,” said Marvel, who helped lead that portion of the research over a six-year period. “The Lehigh faculty have worked on many high-level research projects over the years, and they’ve all taught me different things that I apply now as an academic.”

The ARL was awarded a U.S. patent (US 11,975,385 B2) for the alloy, highlighting its strategic significance, particularly in defense applications like military heat exchangers, propulsion systems and hypersonic vehicles.

Further research will include direct measurements of the alloy’s thermal conductivity compared to nickel-based alternatives, work to ready it for potential applications, and the development of other high-temperature alloys following a similar design strategy.

Exploring quantum materials for a new generation of technology

Today’s technology, from computer chips to camera image sensors, relies heavily on silicon semiconductors, which have been shrinking for decades. However, physical limitations will soon halt further advancements. Consequently, scientists and engineers are developing a new generation of technology based on quantum mechanics. Electrons in “quantum materials” exhibit unique behaviors, such as magnetism and superconductivity, which are crucial for future quantum technologies.

“Our piece of the puzzle is understanding how these materials function as a prerequisite for using them in engineering devices,” said Mark Dean, a physicist at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory and leader of the Dynamics and Control Group in Brookhaven’s Condensed Matter Physics and Materials Science Department.

Dean characterizes quantum materials using a technique called resonant inelastic X-ray scattering, or RIXS. RIXS is particularly suited for probing samples as thin as one atomic layer and material states that change very rapidly. And with recent technological developments, researchers expect this technique to enable studies that were unthinkable only five years ago.

This progress gave Dean and three colleagues — Matteo Mitrano, Steven Johnston, and Young-June Kim — the impetus to chart where the field is going as a whole. So, they summarized the technique’s state of the art and how they expect the field to progress in a Perspective paper.

Scientists observe exotic quantum phase once thought impossible

Rice University researchers have directly observed a superradiant phase transition (SRPT), a quantum phenomenon predicted over 50 years ago, which could revolutionize quantum computing, communication, and sensing. This occurs when quantum particles fluctuate collectively without external triggers, forming a new state of matter. The discovery was made in a crystal of erbium, iron, and oxygen, cooled to minus 457°F and exposed to a magnetic field of up to 7 tesla.

“Originally, the SRPT was proposed as arising from interactions between quantum vacuum fluctuations — quantum light fields naturally existing even in completely empty space — and matter fluctuations,” said Dasom Kim, a Rice doctoral student in the Applied Physics Graduate Program who is a lead author on the study. “However, in our work, we realized this transition by coupling two distinct magnetic subsystems — the spin fluctuations of iron ions and of erbium ions within the crystal.”

Spin describes the magnetic poles of electrons or other particles and can be envisioned as a tiny arrow attached to each particle, constantly twirling and pointing in a given direction. When spins align, they create magnetic patterns across a material. When the pattern of spins ripples across the material like a wave, the resulting collective excitation is known as a magnon.

Until now, whether or not an SRPT could actually take place was subject to debate as it runs against a limitation — called “no-go theorem” in theoretical physics — arising in light-based systems. By staging an SRPT in a magnetic crystal based on the interactions between two spin subsystems, the researchers were able to get around this barrier, creating a magnonic version of the phenomenon. Specifically, the iron ions’ magnons play the role traditionally attributed to vacuum fluctuations, and the erbium ions’ spins represent matter fluctuations.

Using advanced spectroscopic techniques, the researchers observed unmistakable signatures of an SRPT, with the energy signal of one spin mode vanishing and another showing a clear shift or kink. These spectral fingerprints match exactly what theory predicts for entering the superradiant phase, giving the team high confidence that they had indeed coaxed the long-sought state into being.

“We established an ultrastrong coupling between these two spin systems and successfully observed a SRPT, overcoming previous experimental constraints,” Kim said.

Researchers are excited not just because a 50-year-old physics prediction has been confirmed but also because of what this could mean for quantum technology. Collective quantum states at the SRPT have unique properties that could be harnessed for next-generation quantum technologies.

“Near the quantum critical point of this transition, the system naturally stabilizes quantum-squeezed states — where quantum noise is drastically reduced — greatly enhancing measurement precision,” Kim said. “Overall, this insight could revolutionize quantum sensors and computing technologies, significantly advancing their fidelity, sensitivity and performance.”

Sohail Dasgupta, a graduate student at Rice working with Kaden Hazzard, associate professor of physics and astronomy, theoretically modeled the SRPT, building on a model developed by their collaborator and co-author Motoaki Bamba, a professor at Yokohama National University.

“Although the basic mathematical model was already laid out before by Motoaki, we needed to account for some of the specific magnetic properties of the material to obtain the precise results. When your theory matches the experimental data ⎯ which happens rather rarely ⎯ it is the best feeling for a scientist,” Dasgupta said.

Hazzard said the achievement shows that concepts from quantum optics can be translated into solid materials.

“This opens a new way to create and control phases of matter using ideas from cavity quantum electrodynamics,” Hazzard said.

Moreover, the crystal used in this study is one example of a broader class of materials, which means the research paves the way for exploring quantum phenomena in other materials with similarly interacting magnetic components.

Strange behavior in ultra-thin materials

Researchers at the Hebrew University of Jerusalem, led by Ph.D. student Nofar Fridman and Prof. Yonathan Anahory, have discovered unexpected behavior in superconductivity within extremely thin materials. Superconductors, which allow electric current to flow without resistance, typically exhibit predictable changes when thinned. However, the team found surprising results when studying thin films of niobium diselenide (NbSe2), a layered superconducting material. Using advanced magnetic imaging techniques, they measured the material’s response to magnetic fields as its thickness decreased, revealing new insights into superconductivity at the nanoscale.

Typically, scientists expect the ability of a superconducting material to expel magnetic fields to become stronger as the material becomes thicker. Here, this length is gauged by a physical property called the Pearl length. This study confirmed that rule for samples thicker than ten atomic layers. However, when the films became extremely thin—just three to six layers (2-4 nm) —the researchers observed something unexpected: the Pearl length sharply increased and became thickness independent, breaking the expected pattern.

“Our findings reveal something completely unexpected that could be ubiquitous in superconducting materials,” explained Nofar Fridman, the Ph.D. student leading the study. “In very thin samples, superconductivity behaves differently from what we’ve known. It seems that below a certain thickness, superconductors host current mostly at their top and bottom surfaces, rather than throughout their volume. This finding opens up exciting new questions about superconductivity in ultra-thin materials.”

The team’s supervisor, Prof. Yonathan Anahory, emphasized the importance of their method, saying, “Our high-resolution magnetic imaging allowed us to see details that previous methods couldn’t detect. By finding this unique surface superconductivity, we’ve expanded our understanding of how superconducting materials behave at extremely small scales. This could have significant implications for future research and technologies.”

This discovery sheds new light on superconductivity in very thin films and challenges previously held theories. It also highlights how specialized measurement techniques can uncover surprising new physical phenomena, potentially opening avenues for innovative applications in quantum technology.

SLAC fired the most intense submicron electron beam in history

Scientists at SLAC National Accelerator Laboratory have developed an ultrashort electron beam with five times the peak current of any previous beam, addressing a major challenge in particle accelerator and beam physics: generating high-power electron beams without compromising quality. This breakthrough opens new research possibilities in quantum chemistry, astrophysics, and materials science.

“Not only can we create such a powerful electron beam, but we’re also able to control the beam in ways that are customizable and on demand, which means we can probe a much wider range of physical and chemical phenomena than ever before,” said Claudio Emma, a staff scientist at the Department of Energy’s SLAC National Accelerator Laboratory, who is a researcher at SLAC’s Facility for Advanced Accelerator Experimental Tests (FACET-II) and a lead author on the new study.

One of the field’s longstanding goals has been to develop electron beams that are both extremely powerful and precisely controlled. Until now, increasing a beam’s power often meant degrading its quality, a tradeoff that has limited progress in many advanced experiments.

Traditionally, a microwave field is used to compress and focus the electron beam. The electrons within the field are staggered, so that those further back have more energy than those in the front. It’s sort of like runners staggered at the start of a track race, Emma explained. “We then send them around a bend, so the electrons in back catch up with electrons in front, and then at the end, you have a bunch of electrons together in a focused beam.”

The problem with this approach is that as they accelerate, electrons emit radiation and lose energy, so the quality of the beam deteriorates. That creates a tradeoff between beam energy and quality. “We can’t apply traditional methods to compress bunches of electrons at the submicron scale, while also preserving beam quality,” Emma said.

To solve this issue, SLAC researchers compressed billions of electrons into a length less than one micrometer using a laser-based shaping technique originally developed for X-ray free-electron lasers, such as SLAC’s Linac Coherent Light Source (LCLS). “The big advantage of using a laser is that we can apply an energy modulation that’s much more precise than what we can do with microwave fields,” Emma said.

But it’s not as simple as just shooting a few lasers down a tunnel. “We have a one-kilometer-long machine, and the laser interacts with the beam in the first 10 meters, so you have to get the shaping exactly right, then you have to transport the beam for another kilometer without losing this modulation, and you have to compress it,” Emma said. “So it wasn’t easy.”

After several months of testing and finessing their laser shaping technique, Emma and his team can now repeatedly produce high energy, femtosecond-duration, petawatt peak power electron beams that are about five times higher in current than what could previously be achieved.

This new beam will allow scientists to probe a whole series of natural phenomena, including testing hypotheses in quantum physics, materials science, and astrophysics.

In astrophysics, for example, this beam can be directed to a solid or gas target to create a filament similar to those seen in stars. “Scientists know that these filaments occur, but now we can test how they occur and evolve in the lab with a level of power we haven’t had before,” Emma said.

Fellow FACET-II researchers pounced on the more powerful beam and have already applied it to advancing plasma wakefield technology. Emma is particularly excited about the prospect of further compressing these beams to make attosecond light pulses, further enhancing LCLS’s current attosecond capabilities and driving even more pioneering science. “If you have the beam as a fast camera, then you also have a light pulse that’s very short, and now suddenly you have two complementary probes,” Emma explained. “That’s a unique capability and we can do a lot of things with that.”

Emma and his colleagues are excited about the prospects this new electron beam will bring. “We have a really exciting and interesting facility at FACET-II where people can come and do their experiments,” he said. “If you need an extreme beam, we have the tool for you, and let’s work together.”

Chance discovery improves stability of bioelectronic material used in medical implants, computing and biosensors

A chance discovery by scientists from Rice University, University of Cambridge, and Stanford University has streamlined the production of PEDOT:PSS, a material widely used in medical research and computing. For over two decades, a chemical crosslinker was used to stabilize this conductive polymer in water. However, while experimenting with patterning techniques for biomedical optics, Stanford doctoral student Siddharth Doshi, collaborating with Rice’s Scott Keene, found that heating the material at a higher temperature without the crosslinker resulted in a stable sample, eliminating the need for the crosslinker.

“It was more of a serendipitous discovery because Siddharth was trying out processes very different to the standard recipe, but the samples still turned out fine,” Keene said. “We were like, ‘Wait! Really?’ This prompted us to look into why and how this worked.”

What Keene and his team found was that heating PEDOT:PSS beyond the usual threshold not only makes it stable without needing any crosslinker, but it also creates higher quality devices. This method could make bioelectronic devices easier and more reliable to manufacture with potential applications in neural implants, biosensors and next-generation computing systems.

PEDOT:PSS is a blend of two polymers: one that conducts electronic charge and does not dissolve in water and another that conducts ionic charge and is water-soluble. Because it conducts both types of charges, PEDOT:PSS bridges the gap between living tissue and technology.

“It allows you to essentially talk the language of the brain,” said Keene, who researches advanced materials for smaller, high-resolution electrodes capable of both recording and stimulating neural activity with precision.

The human nervous system relies on ions—charged particles like sodium and potassium—to transmit signals, while electronic devices work with electrons. A material that can handle both is crucial for neural implants and other bioelectronic devices that need to translate biological activity into readable data and send signals without damaging sensitive tissue.

In contrast, the higher heat stabilizes PEDOT:PSS by causing a phase change in the material. When heated beyond a certain temperature, the water-insoluble polymer reorganizes internally, pushing the water-soluble components to the surface, where they can be washed away. What remains is a thinner, purer and more stable conducting film.

“This method pretty much simplifies a lot of these problems that people have working with PEDOT:PSS,” Keene said. “It also essentially eliminates a potentially toxic chemical.”

Margaux Forner, a doctoral student at Cambridge who is a first author on the paper along with Doshi, said that heat-treated bioelectronic devices such as transistors, spinal cord stimulators and electrocorticography arrays — implanted grids or strips of neuroelectrodes used to record brain activity — were easier to fabricate, more reliable and equally high performing to those fabricated using the crosslinker.

“The devices made from heat-treated PEDOT:PSS proved to be robust in chronic in vivo experiments, maintaining stability for over 20 days postimplantation,” Forner said. “Notably, the film maintained excellent electrical performance when stretched, highlighting its potential for resilient bioelectronic devices both inside and outside the body.”

The finding may help explain why previous efforts to use PEDOT:PSS in long-term neural implants, including those by Neuralink, ran into stability issues. By making PEDOT:PSS more reliable, this discovery could help advance neurotechnology, including implants to restore movement after spinal cord injuries and interfaces that link the brain to external devices.

Beyond simplifying fabrication, the team found a way to pattern PEDOT:PSS into microscopic 3D structures — a breakthrough that could further improve bioelectronic devices. Using a high-precision femtosecond laser, the researchers can selectively heat sections of the material, creating custom textures that enhance how cells interact with the devices.

By eliminating the crosslinker, the research findings not only streamline the PEDOT:PSS fabrication process but also improve its performance. The new method produces a material with three times higher electrical conductivity and more consistent stability between batches — key advantages for medical applications.

The crosslinker worked by chemically bonding the two types of polymer strands in PEDOT:PSS together, creating an interconnected mesh. However, it still left some of the water-soluble strands exposed — a likely cause for the stability issues. Moreover, the crosslinker introduced variability and potential toxicity in the material.

This technique could be used to design neural interfaces that encourage better integration with surrounding tissue, improving signal quality and longevity.

Keene had also previously researched PEDOT:PSS in the context of neuromorphic memory devices used to accelerate artificial intelligence algorithms. Neuromorphic memory is a type or artificial memory that mimics how the brain retains information.

“It basically emulates the synaptic plasticity of your brain,” Keene said. “We can modify the connection between two terminals by controlling how conductive this material is; this is very similar to how your brain learns by strengthening or weakening synaptic connections between individual neurons.”

By unseating a long-standing assumption, the research not only made PEDOT:PSS easier to work with but also more powerful — a shift that could accelerate the development of safer, more effective neural implants and bioelectronic systems.

Scientists merge two “impossible” materials into new artificial structure

An international team led by Rutgers University-New Brunswick researchers has created a synthetic quantum structure by merging two lab-synthesized materials, previously thought impossible to combine. This exotic structure, developed through four years of experimentation, could provide new insights for quantum computing. The structure consists of distinct atomic layers: dysprosium titanate, used in nuclear reactors to trap radioactive materials and magnetic monopoles, and pyrochlore iridate, a magnetic semimetal known for its unique electronic, topological, and magnetic properties.

Individually, both materials are often considered “impossible” materials due to their unique properties that challenge conventional understanding of quantum physics.

The construction of the exotic sandwich structure sets the stage for scientific explorations in what is referred to as the interface, the area where the materials meet, in the atomic scale.

“This work provides a new way to design entirely new artificial two-dimensional quantum materials, with the potential to push quantum technologies and provide deeper insight into their fundamental properties in ways that were previously impossible,” said Jak Chakhalian, the Claud Lovelace Endowed Professor of Experimental Physics in the Department of Physics and Astronomy at the Rutgers School of Arts and Sciences and a principal investigator the study.

Chakhalian and his team are exploring a realm that follows the laws of quantum theory, a branch of physics that describes the behavior of matter and energy at the atomic and subatomic level. Central to quantum mechanics is the concept of wave-particle duality where quantum objects can possess both wave-like and particle-like properties – a foundational principle behind technologies such as lasers, magnetic resonance imaging (MRI) and transistors.

Chakhalian highly praised the efforts of three Rutgers students who made major contributions to the research: Michael Terilli and Tsung-Chi Wu, both doctoral students, and Dorothy Doughty, who graduated in 2024 and worked on the study as an undergraduate. In addition, Mikhail Kareev, who is a materials scientist working with Chakhalian, made a main contribution to the new synthesis method, as well as Fangdi Wen, a doctoral student who recently graduated from the Department of Physics and Astronomy.

Chakhalian said that creating the unique quantum sandwich was so technically challenging that the team had to build a new device to accomplish the feat.

The instrument, called Q-DiP, short for quantum phenomena discovery platform, was completed in 2023. Q-DiP incorporates an infrared laser heater with another laser which enables the construction of materials on an atomic level, layer by layer. The combination allows the scientists to explore the most intricate quantum properties of materials down to ultra cold temperatures near absolute zero.

“To the best of our knowledge, this probe is unique in the U.S. and represents a breakthrough as an instrumental advance,” Chakhalian said.

The half of the experimental sandwich that is dysprosium titanate, also known as spin ice, possesses special qualities. Tiny magnets inside, called spins, are arranged in a way that looks exactly like the pattern of water ice. The unique structure of the tiny magnets in spin ice allows them to emerge as special particles called magnetic monopoles.

A magnetic monopole is a particle that acts like a magnet, but with only one pole – either north or south, but not both. This object, predicted in 1931 by the Nobel prize winner Paul Dirac, does not exist in free form in the universe and yet inside spin ice it emerges as a result of the quantum mechanical interactions within the material.

On the other side of the sandwich, the semimetal pyrochlore iridate is also considered exotic because it contains tiny relativistic particles called Weyl fermions. Again, surprisingly, though predicted by Hermann Weyl in 1929, these exotic particles, discovered in 2015 in crystals, move like light and can spin in different ways – left-handed or right-handed. Their electronic properties are very strong and resist certain types of disturbances or impurities, making them very stable when operated as a part of electronic devices. As a result, pyrochlore iridate can conduct electricity very well, respond in unusual ways to magnetic fields and show special effects when exposed to electromagnetic fields.

Chakhalian said the combined properties of the new material created makes it a promising candidate for use in advanced technologies, including quantum computing and especially for the next-generation quantum sensors.
“This study is a big step forward in material synthesis and could significantly impact the way we create quantum sensors and advances spintronic devices,” he said.

Quantum computing employs the principles of quantum mechanics to process information. Quantum computers use quantum bits or qubits that exist in multiple states simultaneously due to a quantum physical principle called superposition. This allows for complex computations to be performed much more efficiently than by classical computers.

The specific electronic and magnetic properties of the material developed by the researchers can help in creating very unusual and yet stable quantum states, which are essential for quantum computing.

When quantum technology becomes practical, it will significantly impact ordinary life by revolutionizing drug discovery and medical research, markedly improving operations, predictability and cost savings in finance, logistics and manufacturing. It also is expected to revolutionize machine learning algorithms, making artificial intelligence systems more powerful, the scientists said.

One Minute Mentor: Advantages and Limitations of Heat Treatment Simulation

Heat treatment simulation can be a tool for optimization of heat-treatment processes, but at the present this method is still limited. Therefore most HTS is based on rough simplifications of the process. Simplifications can involve the process, number of phases, transformation kinetics, continuums models instead of micro-mechanical models, etc. These simplifications also result in inaccuracies in the calculations.
