Credit: University of Waterloo Researchers at the University of Waterloo’s Institute for Quantum Computing (IQC) have brought together two Nobel prize-winning research concepts to advance the field […]
Credit: Physical Review Research (2024). DOI: 10.1103/PhysRevResearch.6.013238 U.S. Naval Research Laboratory (NRL) scientists have published the Cascaded Variational Quantum Eigensolver (CVQE) algorithm in a recent Physical Review Research article. The algorithm is expected to become a powerful tool to investigate the physical properties in electronic systems. The CVQE algorithm is a variant of the Variational […]
Experimental setup. 3D reconstruction of fish trajectories with 3 synchronized cameras. The locations of the fish were determined in each 2D image to calculate the 3D coordinates. The 3D coordinates are subsequently linked into 3D trajectories. Credit: Nature Communications (2024). DOI: 10.1038/s41467-024-46426-1 Physicists are also interested in fish—above all when they are researching the formation […]
A magnetic octupole and the three decreasing intensity peaks are predicted to be present in inelastic neutron scattering for π-flux QSI. Credit: Desrochers & Kim Quantum spin liquids are fascinating quantum systems that have recently attracted significant research attention. These systems are characterized by a strong competition between interactions, which prevents the establishment of a […]
Evolution with temperature of polarons in tantalum layers of 1T-TaS2 through different CDW phases: commensurate (C), nearly commensurate (NC), and incommensurate (IC). When CDW is removed at high temperature, polarons are in a gas-like state. Credit: Nature Communications (2023). DOI: 10.1038/s41467-023-42631-6 Research often unfolds as a multistage process. The solution to one question can spark […]
Physics alumna Erin McCarthy ’23, right, was lead author on a study published in Physical Review Letters which uncovered mechanisms that cause particles to sort spontaneously into different groups. Professor M. Lisa Manning, left, was a co-author. Credit: Syracuse University Erin McCarthy ’23, physics summa cum laude, is a rarity among young scientists. As an […]
Mit Laser angeregter Ytterbium-dotierter Glasstab. Bildnachweis: Fraunhofer IOF Einem Forscherteam des Fraunhofer-Instituts für Angewandte Optik und Feinmechanik IOF und der University of New Mexico ist es erstmals gelungen, Quarzglas durch optische Laserkühlung um 67 Kelvin abzukühlen. Die Forscher aus Jena und Albuquerque haben […]
AR-HCF-Querschnittsstruktur. Bildnachweis: Huang Lei Eine Forschungsgruppe unter der Leitung von Prof. Jiang Haihe vom Hefei Institutes of Physical Science der Chinesischen Akademie der Wissenschaften hat eine 6-Loch-Mikrostruktur-Antiresonanz-Luftkernfaser (AR-HCF) mit einem größeren Kerndurchmesser entwickelt von 78 μm. „Dies ist das erste Mal, dass 2.79 μm hochenergetische gepulste […]
Experimenteller Aufbau im Labor zur Erforschung von Schwarzen Löchern. Bildnachweis: Leonardo Solidoro Wissenschaftler haben zum ersten Mal einen riesigen Quantenwirbel geschaffen, der ein Schwarzes Loch in superflüssigem Helium nachahmt und es ihnen ermöglicht, detaillierter zu sehen, wie sich analoge Schwarze Löcher mit ihrer Umgebung verhalten und interagieren. Forschungsgeführt […]
