Superfluid behavior of a Bose-Einstein condensate in a random potential
arXiv:1407.3568 · doi:10.1088/1367-2630/17/1/013022
Abstract
We investigate the relation between Bose-Einstein condensation (BEC) and superfluidity in the ground state of a one-dimensional model of interacting Bosons in a strong random potential. We prove rigorously that in a certain parameter regime the superfluid fraction can be arbitrarily small while complete BEC prevails. In another regime there is both complete BEC and complete superfluidity, despite the strong disorder.
