Glasses do not flow, while superfluids flow without resistance. A phase of matter that is both glassy and superfluid sounds like an oxymoron.
In a recent paper, Professor Claudio Chamon and his collaborators have shown that interacting bosons can form a superglass at a very low temperature and high density. This phase of matter is the amorphous counterpart to supersolids, which may have been observed in He4 experiments. Superglassy phases may also appear in mixtures of cold atoms trapped by lasers in frustrated lattices.
