Washington, Jan 14 : A team of physicists has proposed a recipe for turning ultracold "boson" atoms into a "supersolid," an exotic state of matter that behaves simultaneously as a solid and a friction-free superfluid.
The physicists were from the Joint Quantum Institute (JQI) of the National Institute of Standards and Technology (NIST) and the University of Maryland in the US.
While scientists have found evidence for supersolids in complex liquid helium mixtures, a supersolid formed from such weakly interacting gas atoms would be simpler to understand, potentially providing clues for making a host of new "quantum materials" whose bizarre properties could expand physicists' notions of what is possible with matter.
