Our method is based on quantitative estimates on the discrepancy between the full many-body energy and its mean-field approximation using Hartree states. These are proved using finite dimensional localization and a quantitative version of the quantum de Finetti theorem. Our approach covers the case of attractive interactions in the regime of stability. In particular, our main new result is a derivation of the 2D attractive non-linear Schrödinger ground state."}],"year":"2016","title":"The mean-field approximation and the non-linear Schrödinger functional for trapped Bose gases","month":"01","doi":"10.1090/tran/6537","oa_version":"Submitted Version","department":[{"_id":"RoSe"}],"publication":"Transactions of the American Mathematical Society","status":"public"}
