In the coexistence phase where both components are superfluid, interspecies interactions induce a nondissipative drag between the two superfluid flows (Andreev-Bashkin effect). We show that this behavior leads to a modification of the usual Berezinskii-Kosterlitz-Thouless (BKT) transition in two dimensions. We extend the renormalization of the superfluid densities at finite temperature using the renormalization-group approach and find that the vortices of one component have a large influence on the superfluid properties of the other, mediated  by  the  nondissipative  drag.  The  extended  BKT  flow  equations  indicate  that  the  occurrence  of  the vortex unbinding transition in one of the components can induce the breakdown of superfluidity also in the other, leading to a locking phenomenon for the critical temperatures of the two gases.","lang":"eng"}],"volume":99,"external_id":{"isi":["000473133600007"],"arxiv":["1903.06759"]},"status":"public","publication":"Physical Review A","publication_status":"published","issue":"6","oa":1,"main_file_link":[{"url":"https://arxiv.org/abs/1903.06759","open_access":"1"}],"intvolume":"        99","month":"06","article_number":"063627","doi":"10.1103/PhysRevA.99.063627","article_processing_charge":"No","date_created":"2019-07-14T21:59:17Z","date_published":"2019-06-28T00:00:00Z","_id":"6632","publisher":"American Physical Society","quality_controlled":"1","oa_version":"Preprint","date_updated":"2024-02-28T13:12:34Z","scopus_import":"1","type":"journal_article","day":"28","publication_identifier":{"issn":["24699926"],"eissn":["24699934"]},"year":"2019"}
