Theorem unifies superfluids and other weird materials

Theorem unifies superfluids and other weird materials – University of California, Berkeley, physicist Hitoshi Murayama and graduate student Haruki Watanabe have discovered a commonality among these materials that can be used to predict or even design new materials that will exhibit such unusual behavior. The theory applies equally to magnets, crystals, neutron stars, and cosmic strings. Reference: H. Watanabe and H.
