We consider the interaction potential to be given either by Wβ(x)=N−1+2βW(Nβx), for any β>0, or to be given by VN(x)=e2NV(eNx), for some spherical symmetric, nonnegative and compactly supported W,V∈L∞(R2,R). In both cases we prove the convergence of the reduced density corresponding to the exact time evolution to the projector onto the solution of the corresponding nonlinear Schrödinger equation in trace norm. For the latter potential VN we show that it is crucial to take the microscopic structure of the condensate into account in order to obtain the correct dynamics.","lang":"eng"}],"oa_version":"Published Version","article_type":"original","month":"11","publication_identifier":{"eissn":["1432-0916"],"issn":["0010-3616"]},"project":[{"name":"Analysis of quantum many-body systems","_id":"25C6DC12-B435-11E9-9278-68D0E5697425","call_identifier":"H2020","grant_number":"694227"},{"name":"IST Austria Open Access Fund","_id":"B67AFEDC-15C9-11EA-A837-991A96BB2854"}],"intvolume":" 372","ddc":["510"],"date_published":"2019-11-08T00:00:00Z","department":[{"_id":"RoSe"}],"title":"Derivation of the time dependent Gross–Pitaevskii equation in two dimensions","article_processing_charge":"Yes (via OA deal)","language":[{"iso":"eng"}],"type":"journal_article","user_id":"3E5EF7F0-F248-11E8-B48F-1D18A9856A87","publication":"Communications in Mathematical Physics","status":"public","year":"2019","date_updated":"2020-01-16T12:38:17Z","acknowledgement":"OA fund by IST Austria","file_date_updated":"2019-11-25T08:11:11Z","_id":"7100","citation":{"short":"M.
