A research team at the University of Wyoming created an innovative method to control tiny magnetic states within ultrathin, two-dimensional (2D) van der Waals magnets -- a process akin to how flipping a light switch controls a bulb.

By tinkering with a quantum material characterized by atoms arranged in the shape of a sheriff’s star, MIT physicists and colleagues have unexpectedly discovered a new way to make a state of matter known as a strange metal. Strange metals are of interest for their unusual physics and because they have been found in the high-temperature superconductors key to a variety of applications.

In a recent collaboration between the High Magnetic Field Center of the Hefei Institutes of Physical Science of Chinese Academy of Sciences, and the University of Science and Technology of China, researchers introduced the concept of the "Topological Kerr Effect" (TKE) by utilizing the low-temperature magnetic field microscopy system and magnetic force microscopy imaging system supported by the steady-state high magnetic field experimental facility.

In a significant development in the field of superconductivity, researchers at The University of Manchester have successfully achieved robust superconductivity in high magnetic fields using a newly created one-dimensional (1D) system. This breakthrough offers a promising pathway to achieving superconductivity in the quantum Hall regime, a longstanding challenge in condensed matter physics.

Single-photon emitters (SPEs) are akin to microscopic lightbulbs that emit only one photon (a quantum of light) at a time. These tiny structures hold immense importance for the development of quantum technology, particularly in applications such as secure communications and high-resolution imaging. However, many materials that contain SPEs are impractical for use in mass manufacturing due to their high cost and the difficulty of integrating them into complex devices.

A USC computer scientist wants to produce quantum materials at scale, with help from Argonne supercomputers.

Scientists have taken the first atomic-resolution images of an exotic quantum phenomenon that could help researchers advance quantum computing and energy-efficient electronics. The work enables the visualization and control of electron flow in a unique class of quantum insulators. The findings may help researchers build tunable networks of electron channels with promise for efficient quantum computing and low-power magnetic memory devices in the future.

Scientists have for the first time successfully visualized the elusive Wigner crystal – a strange form of matter that is one of the most important quantum phases and one that has eluded direct detection for some 90 years.

Physicists have observed a novel quantum effect termed “hybrid topology” in a crystalline material. This finding opens up a new range of possibilities for the development of efficient materials and technologies for next-generation quantum science and engineering.

A major soon-to-begin project aims to develop these critical building blocks to enable future quantum devices. Peter Liljeroth, professor of physics at Aalto University and director of the new Finnish Quantum Flagship, has received a 2,5 million euro grant from the European Research Council for research on quantum materials. The project will start at the turn of the year, and it is hoped to enable technologies that we may not yet even be able to imagine.
