In a new study, researchers from the MCQST, the Max Planck Institute of Quantum Optics and the LMU under the lead of Timon Hilker demonstrated evidence of stripe formation, i.e. extended structures in the density pattern, in a cold-atom Fermi-Hubbard system. By using a quantum gas microscope and a special mixed-dimensional geometry, they were able to observe unique higher-order correlations in spin and charge densities related to those seen in some high-temperature superconducting materials.

A research team coordinated by the Department of Physics was able to work on the powerful computers of Google's Quantum Artificial Intelligence Lab to conduct a study on confinement in lattice gauge theory. The results of the study have been published in Nature Physics.

A research team led by The Hong Kong University of Science and Technology (HKUST) has achieved a groundbreaking quantum simulation of the non-Hermitian skin effect in two dimensions using ultracold fermions, marking a significant advance in quantum physics research.

Recently, a research team led by Prof. LI Chuanfeng from the University of Science and Technology of China (USTC) achieved a breakthrough in quantum photonics. They developed an on-chip photonic simulator capable of simulating arbitrary-range coupled frequency lattices with gauge potential. This study was published in Physical Review Letters.

The magnetic moment of the muon is an important precision parameter for putting the Standard Model of particle physics to the test. After years of work, the research group led by Professor Hartmut Wittig of the PRISMA+ Cluster of Excellence at Johannes Gutenberg University Mainz (JGU) has calculated this quantity using the so-called lattice quantum chromodynamics method (lattice QCD method). Their result, which was recently published, agrees with the latest experimental measurements, in contrast to earlier theoretical calculations. After the experimental measurements had been pushed to ever higher precision in recent years, attention had increasingly turned to the theoretical prediction and the central question of whether it deviates significantly from the experimental results and thus provides evidence for the existence of new physics beyond the Standard Model.

Now, researchers at NYU Tandon School of Engineering led by Elisa Riedo, Herman F. Mark Professor in Chemical and Biomolecular Engineering, have uncovered a new phenomenon in graphene research, observing growth-induced self-organized ABA and ABC stacking domains that could kick-start the development of advanced quantum technologies. The findings, published in a recent study in the Proceedings of the National Academy Of Sciences (PNAS), demonstrate how specific stacking arrangements in three-layer epitaxial graphene systems emerge naturally — eliminating the need for complex, non-scalable techniques traditionally used in graphene twisting fabrication.

Researchers at the UChicago Pritzker School of Molecular Engineering (UChicago PME) have realized a new design for a superconducting quantum processor, aiming at a potential architecture for the large-scale, durable devices the quantum revolution demands.

A new study by Rice University physicist Qimiao Si unravels the enigmatic behaviors of quantum critical metals — materials that defy conventional physics at low temperatures. Published in Nature Physics Dec. 9, the research examines quantum critical points (QCPs), where materials teeter on the edge between two distinct phases such as magnetism and nonmagnetism. The findings illuminate the peculiarities of these metals and provide a deeper understanding of high-temperature superconductors, which conduct electricity without resistance at relatively high temperatures.

A research team led by Dominik Schneble, PhD, Professor in the Department of Physics and Astronomy, has uncovered a novel regime, or set of conditions within a system, for cooperative radiative phenomena, casting new light on a 70-year-old problem in quantum optics.

In this study, researchers from a large international team including ANSTO, investigated the magnetic properties of two unique 2D triangular lattice antiferromagnetic materials (2D-TLHAF)* using various neutron scattering techniques.
