This is a repulsive nonlinear Schrödinger functional whose quartic term is proportional to the scattering length of the interparticle interaction potential. We propose a new derivation of this limit problem, with a method that bypasses some of the technical difficulties that previous derivations had to face. The new method is based on a combination of Dyson\\'s lemma, the quantum de Finetti theorem and a second moment estimate for ground states of the effective Dyson Hamiltonian. It applies equally well to the case where magnetic fields or rotation are present.","lang":"eng"}],"quality_controlled":"1","status":"public","department":[{"_id":"RoSe"}],"publist_id":"6215","type":"journal_article","volume":9,"scopus_import":1,"publication":"Analysis and PDE","project":[{"grant_number":"291734","_id":"25681D80-B435-11E9-9278-68D0E5697425","call_identifier":"FP7","name":"International IST Postdoc Fellowship Programme"}],"page":"459 - 485","citation":{"apa":"Nam, P., Rougerie, N., &#38; Seiringer, R.
