Experimental evidence adds to the likelihood of the existence of supersolids, an exotic phase of matter
Supersolids and superfluids rank among the most exotic of quantum mechanical phenomena. Superfluids can flow without any viscosity, and experience no friction as they flow along the walls of a container, because ...
