'Supersolids' confirmed as new state of matter
MIT physicists have created a new state of matter, a supersolid, which simultaneously behaves like a solid and a liquid. The structure was obtained by laser-cooling a superfluid gas called as 'Bose-Einstein condensate' at nearly absolute zero temperature (-273ºC) under ultrahigh-vacuum conditions. The supersolid shows symmetry breaking properties and a free-flowing behaviour, scientists said.
