In another regime there is both complete BEC and complete superfluidity, despite the strong disorder"}],"article_number":"013022","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","has_accepted_license":"1","publication_status":"published","year":"2015","quality_controlled":"1","oa":1,"day":"15","status":"public","citation":{"ista":"Könenberg M, Moser T, Seiringer R, Yngvason J. 2015.
