Here, a is the scattering length of the repulsive interaction potential and ρ is the density. To the leading order in a2 ρ, this bound agrees with the expected critical temperature for superfluidity. In the three-dimensional Bose gas, exponential decay is proved when T- Tc (0) Tc (0) >5 a ρ1/3, where Tc (0) is the critical temperature of the ideal gas. While this condition is not expected to be sharp, it gives a rigorous upper bound on the critical temperature for Bose-Einstein condensation.","lang":"eng"}],"date_created":"2018-12-11T11:57:22Z","status":"public","date_updated":"2021-01-12T06:57:10Z","intvolume":" 80","publication":"Physical Review B - Condensed Matter and Materials Physics","date_published":"2009-06-02T00:00:00Z","quality_controlled":0,"day":"02","year":"2009","extern":1,"author":[{"full_name":"Robert Seiringer","first_name":"Robert","orcid":"0000-0002-6781-0521","id":"4AFD0470-F248-11E8-B48F-1D18A9856A87","last_name":"Seiringer"},{"full_name":"Ueltschi, Daniel","first_name":"Daniel","last_name":"Ueltschi"}],"publist_id":"4540","main_file_link":[{"open_access":"1","url":"http://arxiv.org/abs/0904.0050"}]}
