Supersolids, created using lasers, have some unusual properties Chris Rogers/Getty Images
Some solids can be stirred. Researchers have shown that a bizarre quantum state of matter that is both a solid and a frictionless fluid at the same time can be agitated, apparently creating a series of tiny vortices inside the material. The experiment is evidence of the progress being made in understanding the strange properties of so-called 鈥渟upersolids鈥.
鈥淚’ve never done, in all my life, such a challenging experiment,鈥 says at the University of Innsbruck in Austria. In 2022, she and her colleagues became the…
