Supersolids produced in exotic state of quantum matter
Superfluid Bose-Einstein condensates created with crystal structure
SUPER STRIPES Stripes of high- and low-density material form in a system called a Bose-Einstein condensate, shown above in a computer simulation. The pattern indicates that the material is a solid, yet it is also a liquid. Such materials are called supersolids, and scientists have now created them in the laboratory.
