A research team at the Department of Energy’s Oak Ridge National Laboratory created a novel advanced microscopy tool to “write” with atoms, placing those atoms exactly where they are needed to give a material new properties.

An international team from LMU, Harvard University and the Institute of Materials Science in Japan has successfully demonstrated the detection of individual photons in the infrared spectrum by utilizing a revolutionary material called magic-angle twisted bilayer graphene. This discovery represents a significant step towards extending superconducting single-photon detection to longer-wavelength photons. The results are featured in Science Advances.

Researchers from the National University of Singapore (NUS) have developed a new design concept for creating next-generation carbon-based quantum materials, in the form of a tiny magnetic nanographene with a unique butterfly-shape hosting highly correlated spins. This new design has the potential to accelerate the advancement of quantum materials which are pivotal for the development of sophisticated quantum computing technologies poised to revolutionise information processing and high density storage capabilities.

Yale researchers, in collaboration with scientists from City University of New York, California Institute of Technology, Kansas State University and ETH Zurich, leveraged the unusual properties of phonon-polaritons, a type of quasiparticle, to discover a new way to dissipate the energy of high-speed electrons through the generation of long wavelength infrared light.

Newly published research in the journal Nature demonstrates a new way of generating long-wave infrared and terahertz waves, which is an important step toward creating materials that can help realize these technological advances. The work, led by researchers at the CUNY ASRC paves the way for cheaper, smaller long-wave infrared light sources and more efficient device cooling.

ICFO researchers, in an international collaboration, have used terahertz light to explore exotic phenomena within magic-angle twisted bilayer graphene. This approach reveals previously unseen behaviors and provides direct insights into the quantum geometry of electronic wavefunctions —the fundamental framework underlying these phenomena.

The ability to conduct heat is one of the most fundamental properties of matter, crucial for engineering applications. Scientists know well how conventional materials, such as metals and insulators, conduct heat. However, things are not as straightforward under extreme conditions such as temperatures close to absolute zero combined with strong magnetic fields, where strange quantum effects begin to dominate. This is particularly true in the realm of quantum materials. Researchers from the Helmholtz-Zentrum Dresden-Rossendorf (HZDR), University of Bonn, and Centre national de la recherche scientifique (CNRS) now exposed the semimetal zirconium pentatelluride (ZrTe5) to high magnetic fields and very low temperatures. They found dramatically enhanced heat oscillations caused by a novel mechanism. This finding challenges the widely held belief that magnetic quantum oscillations should not be detectable in the heat transport of semimetals, as the scientists report in the journal PNAS.

Scientists from the RIKEN Center for Emergent Matter Science (CEMS) and collaborators have discovered a groundbreaking way to control superconductivity—an essential phenomenon for developing more energy-efficient technologies and quantum computing—by simply twisting atomically thin layers within a layered device. By adjusting the twist angle, they were able to finely tune the “superconducting gap,” which plays a key role in the behavior of these materials. The research was published in Nature Physics.

A research team led by Professor Sun Qing-Feng in colloboration with Professor He Lin’s research group from Beijing Normal University has achieved orbital hybridization in graphene-based artificial atoms for the first time. Their findings, entitled “Orbital hybridization in graphene-based artificial atoms” was published in Nature. This work marks a significant milestone in the field of quantum physics and materials science, bridging the gap between artificial and real atomic behaviors.

University of Texas at Dallas scientists are investigating how structures made from several layers of graphene stack up in terms of their fundamental physics and their potential as reconfigurable semiconductors for advanced electronics.
