Abstract:A quantum solid is intrinsically 'restless', in the sense that atoms continuously vibrate about their position and exchange places even at the absolute zero of temperature. The archetypal quantum solid is low density solid helium. This paper describes some recent experiments done on solid He which illuminate the distinction of a quantum solid from a classical one, and relate some of these properties to new theoretical predictions.
