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.

Researchers have pioneered the use of parallel computing on graphics cards to simulate acoustic turbulence. This type of simulation, which previously required a supercomputer, can now be performed on a standard personal computer. The discovery will make weather forecasting models more accurate while enabling the use of turbulence theory in various fields of physics, such as astrophysics, to calculate the trajectories and propagation speeds of acoustic waves in the universe. The research, supported by a from the Russian Science Foundation (RSF), was in Physical Review Letters.

In a cold-atom Fermi Hubbard model, researchers observed extended and attractive correlations between hole dopants and indications of stripes that are associated with superconductivity, opening up novel insights into the behaviour of exotic quantum phases.

In a new study, researchers from the Max Planck Institute of Quantum Optics 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. These findings, which shed light on a key phenomenon in condensed matter physics, suggest that individual stripe structures could form at higher temperatures than the much-debated stripe phase. This experiment represents a major step forward in using quantum simulators to explore the most fundamental properties of materials. The work is published this week in Nature.

Israel’s first domestically built quantum computer, utilizing advanced superconducting technology, is now operational. The 20-qubit quantum computer was developed under the leadership of the Israel Innovation Authority, Israel Aerospace Industries (IAI), Hebrew University, and the university’s technology transfer company, Yissum. This collaboration established a superconductor-based quantum computer infrastructure alongside a robust development and integration environment. These advancements mark a strategic knowledge foundation for Israel, supporting both defense and civilian applications.

A Japanese research team, led by Professor Dr. Toru Asahi, Researcher Dr. Kenta Nakagawa, and master’s student Keigo Tokita from the Faculty of Science and Engineering, Comprehensive Research Organization at Waseda University, investigated the origin of the strong optical anisotropy of lead-doped Bi2212 single crystals using ultraviolet and visible light transmittance measurements.

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.

Physicist Christian Schneider has been awarded one of the European Research Council's coveted Consolidator Grants. His project focuses on a special group of so-called two-dimensional materials and their optical properties.

While atoms are known to wiggle very fast, dopants added to a cuprate superconductor can also cause atoms to meander very slowly. A SLAC study shows this process, called atomic relaxation, offers a new way to explore quantum states in these puzzling materials.

Quantum computer manufacturing specialist SDT, announced that it has successfully raised KRW 20 billion (USD 14 million) in a pre-IPO funding round. This achievement marks a significant milestone as the company accelerates its plans to become Korea’s first publicly listed quantum technology firm by the second half of 2025.
