Massachusetts Institute of Technology (MIT) investigators say that in a recent study they were able to observe a gas transitioning into a superfluid. The latter is a state of matter in which particles flow past each other without experiencing any kind of friction.
This elusive phase transition is a more advanced fo... |

A new class of quantum materials is hinted at theoretically by researchers at National Institute of Standards and Technology (NIST) Joint Quantum Institute (JQI) and the University of Maryland. They propose a new method of turning ultracold gas atoms into a supersolid, which is a state of matter that behaves very int... |

Supersolidity was first predicted in 1969 by the Russian theorists Alexander Andreev and Ilya Liftshitz.Supersolids are, spatially ordered materials (solids or crystals) with superfluid properties. Along with superfluids, they represent another state of matter, besides the previously known ones: solids, liquids, gas... |

Superfluidity is a phase of matter or description of heat capacity, in which, superconductivity and "unusual" effects are observed when liquids, typically of helium-3, helium-4 or hydrogen, overcome friction by surface interaction when at a stage, known as "lambda point", at which the liquid's viscosity becomes... |
