@article{1880, 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}, author = {Könenberg, Martin and Moser, Thomas and Seiringer, Robert and Yngvason, Jakob}, journal = {New Journal of Physics}, publisher = {IOP Publishing Ltd.}, title = {{Superfluid behavior of a Bose-Einstein condensate in a random potential}}, doi = {10.1088/1367-2630/17/1/013022}, volume = {17}, year = {2015}, }
