[Image courtesy of Adobe Stock] An international team led by Keun Su Kim at Yonsei University has directly measured the quantum metric tensor, also called the quantum distance, in a real material for the first time. Using angle-resolved photoemission spectroscopy (ARPES) at the U.S. Advanced Light Source, researchers mapped how electrons in black phosphorus interact…
Physicists create supersolid state of light, blending properties of liquids and solids
Light: it’s fast, massless, and goes straight through stuff. Right? Well, physicists in Italy just said, “Hold my espresso,” and turned light into something that’s both a solid and a liquid. Yes, you read that correctly. They’ve created a supersolid out of light, a feat previously thought to be the exclusive domain of ridiculously cold atoms. Researchers in Italy have…
