Superglass

From Wikipedia, the free encyclopedia

A superglass is hypothetical phase of matter which is characterized by superfluidity and a frozen amorphous structure at the same time.[1] This idea was put forward by Anthony James Leggett in 1970.[1][2]

In 2009, J.C. Séamus Davis theorised that frozen helium-4 (at 0.2 K and 50 atm) may be a superglass.[1][3][4]
