The Wiedemann-Franz law, which states that the ratio of electronic conductivity to thermal conductivity is constant in metals, has been the foundation of understanding electrical and heat conductivity for over 170 years. However, recent experimental findings in quantum materials, where electrons behave collectively rather than individually, have challenged this long-held law. Physicists from the Department

Fluid behavior and the interplay of waves generated by hydraulic jumps have been the focus of a recent study published in Physical Review Letters. The study explores how small water jets can create stable periodic oscillations on a solid disk, shedding light on the dynamic nature of fluid behavior. This phenomenon, known as a hydraulic
Strange metals have long been a subject of intrigue in the realm of quantum physics. In a recent study conducted at Rice University, researchers delved into the elusive nature of these quantum materials by examining quantum charge fluctuations, also known as “shot noise” [1]. The results of this study provide novel evidence that electricity flows
Researchers have achieved a significant breakthrough in the field of quantum mechanical control of chemical reactions. By utilizing a combination of two extreme-ultraviolet (XUV) light sources, they were able to selectively excite a molecule, causing it to dissociate while simultaneously tracking its progress over time. This advancement holds great potential in enabling new reaction channels
Forensic science has always been an intriguing field for its ability to uncover hidden truths, and bloodstain analysis is no exception. In recent years, the popularity of true crime media has captivated the public’s imagination, shedding light on the importance of scientific methods in deciphering crime scenes. In a groundbreaking study published in the journal
In a groundbreaking study led by the University of Bristol, quantum scientists have recently uncovered a rare and extraordinary phenomenon within purple bronze. This one-dimensional metal, composed of individual conducting chains of atoms, exhibits two opposing electronic states: an insulating state and a superconducting state. What makes this discovery truly remarkable is the material’s ability
