Shaking down frozen helium: In a 'supersolid' state, it has liquid-like characteristics
In a four-decade, Holy Grail-like quest to fully understand what it means to be in a "supersolid" state, physicists have found that supersolid isn't always super solid. In other words, this exotic state of frozen helium appears ...
