In a study published online in Nature, a research team led by Prof. PAN Jianwei, Prof. CHEN Yuao, and Prof. YAO Xingcan from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences has, for the first time, observed the antiferromagnetic phase transition within a large-scale quantum simulator of the fermionic Hubbard model (FHM).

Using artificial intelligence, scientists can now identify complex quantum phases in materials in just minutes—a process that used to take months. The breakthrough, published in Newton, could significantly speed up research into quantum materials, particularly low dimensional superconductors. The study, a collaboration between Yale and Emory University, was seeded by a multi-institute collaboration initiative three years ago. Yale’s side of the research, led by Jinming Yang, a graduate research assistant, and Yu He, assistant professor of Yale’s Department of applied physics, was initiated under a Yale Materials Research Science and Engineering Centers (MRSEC) internal preparatory project awarded in 2022. Other senior authors include Fang Liu and Yao Wang, assistant professors in Emory’s Department of Chemistry.

The scientific community has faced a significant challenge in understanding what drives the complex behaviors, particularly the superconductivity of kagome materials. New research led by Zhenglu Li, assistant professor of materials science at the USC Viterbi School of Engineering, uses a computational approach to unlock the mystery of kagome superconductors, offering unique insights into the way electrons interact with the lattice dynamics.

Now a team led by Nadj-Perge that includes Lingyuan Kong, AWS quantum postdoctoral scholar research associate, and other colleagues at Caltech has discovered a new superconducting state—a finding that provides a new piece of the puzzle behind this mysterious but powerful phenomenon. A paper about the work was published on March 19 in the journal Nature.

An international research team led by QuTech has realised a three-site Kitaev chain using semiconducting quantum dots coupled by superconducting segments in a hybrid InSb/Al nanowire. When comparing two-and three-site chains within the same device, they observed that extending the chain to three sites increased the stability of the zero-energy modes. This work demonstrates the scalability of quantum-dot-based Kitaev chains and their potential to host stable Majorana zero modes. The researchers published their results in Nature Nanotechnology.

Researchers at the Hebrew University of Jerusalem have made a surprising discovery about how superconductivity behaves in extremely thin materials. Superconductors are materials that allow electric current to flow without resistance, which makes them incredibly valuable for technology. Usually, the properties of superconductors change predictably when the materials become thinner; however, this study found something unexpected.

The same layered material can be made to behave as a superconductor, metal, semiconductor or insulator by using a transistor device developed by RIKEN physicists to tweak its electronic properties. The method could help to uncover new superconductors.

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.

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.

Scientists at the Universities of Basel and Cologne have revealed a key superconducting effect in topological insulator nanowires. Their findings bring topological insulator nanowires closer to serving as the foundation for stable, next-generation quantum bits (qubits).
