Workshop on emergence of new states of matter in

A team of physicists from New York University, University of Buffalo, and Wayne State University have discovered a new state of matter, which they say has the potential to increase storage capabilities in electronic devices. The discovery is not yet in an academic journal, but has been published in arXivwhich hosts preprints approved for posting after moderation without full peer review. Titled "Phase signature of topological transition in Josephson Junctions," the paper is focused squarely in the realm of quantum computing.

Quantum computing allows computers to make exponentially fast computations through using what are known as qubits: advances made upon the basics of computer memory, or bits.

Bits are binary, read in 1s and 0s. Qubits, though, allow for computers to read any number between 0 and 1, allowing for much faster calculations.

During this research, the team was able to witness the transition of quantum state from its conventional state to a new topological state, which is to say it took on new geometric properties. Topological states can change during everyday life as well, like when a piece of paper goes from having no rips to being ripped halfway down. They were able to study the quantum state's change by observing the energy barrier between the two states. Within this state of transformation, scientists were able to observe what are known as Majorana particles, named after 20th century Italian theoretical physicist Ettore Majorana.

The Italian scientists theorized the particles, which act as their own antiparticles, in Scientists see them as potential storage for qubits, with the ability to keep quantum information in a special computation space, safe from outside environmental noise.

The catch has always been that there's no natural storage material for these storage particles. But this new state of matter appears to be able to store Majorana particles, which could hold them. With a holding place intact, the Majorana particles could then store qubits.

More From Science.Even by the standards of quantum physicists, strange metals are just plain odd. The materials are related to high-temperature superconductors and have surprising connections to the properties of black holes. Generating a theoretical understanding of strange metals is one of the biggest challenges in condensed matter physics.

Now, using cutting-edge computational techniques, researchers from the Flatiron Institute in New York City and Cornell University have solved the first robust theoretical model of strange metals.

The work reveals that strange metals are a new state of matter, the researchers report July 22 in the Proceedings of the National Academy of Sciences. In the quantum mechanical world, electrical resistance is a byproduct of electrons bumping into things. As electrons flow through a metal, they bounce off other electrons or impurities in the metal. For typical metals, electrical resistance increases with temperature, following a complex equation.

But in unusual cases, such as when a high-temperature superconductor is heated just above the point where it stops superconducting, the equation becomes much more straightforward. Consequently, strange metals are also known as Planckian metals.

Models of strange metals have existed for decades, but accurately solving such models proved out of reach with existing methods. Cha and his colleagues employed two different methods to crack the problem. With this method, instead of performing detailed computations across the whole quantum system, physicists perform detailed calculations on only a few atoms and treat the rest of the system more simply.

They then used a quantum Monte Carlo algorithm named for the Mediterranean casinowhich uses random sampling to compute the answer to a problem. The researchers solved the model of strange metals down to absolute zero minus The resulting theoretical model reveals the existence of strange metals as a new state of matter bordering two previously known phases of matter: Mott insulating spin glasses and Fermi liquids.

It is a sluggish, soupy, slushy state. The new work could help physicists better understand the physics of higher-temperature superconductors. Perhaps surprisingly, the work has links to astrophysics.

There are three forms of matter: solids, liquids and gases. But that's not even half right. There are at least six: solids, liquids, gases, plasmas, Bose-Einstein condensates, and a new form of matter called "fermionic condensates" just discovered by NASA-supported researchers.

349th Knowledge Seekers Workshop; October 8, 2020

Most second graders can recite the properties of ordinary solids, liquids, and gases. Solids resist deformation. They're stiff and they can crumble. Liquids flow, they're hard to compress, and they assume the shape of their container.

Gases are less dense, they're easy to compress, and they not only assume the shape of their container The fourth form of matter, the plasma, is gas-like, made of atoms that have been ripped apart into ions and electrons. The sun is made of plasma, as is most of the matter in the universe. Plasmas are usually very hot, and you can keep them in magnetic bottles. Now we have fermionic condensates--so new that most of their basic properties are unknown. Certainly they're cold.

Jin created the substance by cooling a cloud ofpotassium atoms to less than a millionth of a degree above absolute zero. And they probably flow without viscosity. Beyond that? Researchers are still learning. Fermionic condensates are related to BECs.

Both are made of atoms that coalesce at low temperatures to form a single object.These observations led physicists to theorize about some kind of phase transition—one that would be present in theoretical models of disordered materials as well as actual materials like glass. Yaida used algebra and particle physics to calculate and prove — by hand, no less — that some kinds of glass at low temperatures may exist within a new state of matter.

This changes when and how they break, and how they respond to stress, heat, and sound. The breakthrough here is that the phase transition can exist, not just in a theoretical Universe with infinite numbers of dimensions, but also in a real world setting.

In March of this year, MIT researchers created a new form of matter, a supersolidthat could be key in improving efficient energy transport. Then in April, researchers discovered another new state of matter: 3D quantum liquid crystals that may advance microchip technology and quantum computing.

In the case of this discovery, the proof that the phase transition can actually exist will mean that research questions might be approached in new ways. And if you start shearing the glass, how it will yield, how it will break. Privacy Settings. Share to Facebook.

Next Article.A recent discovery by University of Arkansas physicists could help researchers establish the existence of quantum spin liquids, a new state of matter.

They've been a mystery since they were first proposed in the s. If proven to exist, quantum spin liquids would be a step toward much faster, next-generation quantum computing.

Scientists have focused attention and research on the so-called Kitaev-type of spin liquid, named in honor of the Russian scientist, Alexei Kitaev, who first proposed it. In particular, they have looked extensively at two materials -- RuCl3 and Na2IrO -- as candidates for this type. Both have small quantum spin numbers.

In their recent work, U of A physicists have greatly expanded the number of materials that might be candidates as Kitaev quantum spin liquids by looking at materials with higher quantum spin numbers, and by putting materials under physical strain to tune their magnetic states.

Quantum spin liquids are defined by their unusual magnetic arrangement. Magnets have a north and south pole, which combined are called dipoles. These are typically produced by the quantum spin of electrons. Inside a magnetic material, dipoles tend to all be parallel to each other ferromagnetism or periodically alternate their up and down direction antiferromagnetism. In the case of hypothetical quantum spin liquids, dipoles aren't as well ordered.

Instead, they exhibit unusual ordering within a small distance of each other. Different ordering creates different types of spin liquids. Xu, along with Distinguished Professor of Physics Laurent Bellaiche and colleagues in China and Japan, used computational models to predict a Kitaev quantum spin liquid state in materials such as chromium iodide and chromium germanium telluride.

The work, which was supported by grants from the Arkansas Research Alliance and the Department of Energy, will give researchers many more materials to study in a search to prove the existence of quantum spin liquids, said Xu.
