A crack in the case for supersolids

New experiments are casting doubt on previously reported observations of supersolid helium. In a paper appearing in the current issue of Physical Review Letters, John Reppy (Cornell University) presents research suggesting that p ...

Frictionless supersolid a step closer

Superfluid mixtures of atoms can boil and freeze at ultra-low temperatures. This freezing can result in the formation of supersolids of atoms that can flow alongside each other without friction, but are still set in a fixed ...
