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"}],"publisher":"IOP Publishing Ltd.","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","publist_id":"5214","intvolume":"        17","language":[{"iso":"eng"}],"year":"2015","date_updated":"2021-01-12T06:53:48Z","day":"15","publication":"New Journal of Physics","doi":"10.1088/1367-2630/17/1/013022","scopus_import":1,"file_date_updated":"2020-07-14T12:45:20Z","acknowledgement":"Support from the Natural Sciences and Engineering Research Council of Canada NSERC (MK and RS) and from the Austrian Science Fund FWF (JY, under project P 22929-N16) is gratefully acknowledged","date_created":"2018-12-11T11:54:30Z","date_published":"2015-01-15T00:00:00Z","title":"Superfluid behavior of a Bose-Einstein condensate in a random potential","project":[{"name":"NSERC Postdoctoral fellowship","_id":"26450934-B435-11E9-9278-68D0E5697425"}],"citation":{"ieee":"M.
