Nevertheless, several decades of research failed to establish the validity of spin-wave theory rigorously, even for the simplest models of quantum spins. A rigorous justification of the method for the three-dimensional quantum Heisenberg ferromagnet at low temperatures is presented here. We derive sharp bounds on its free energy by combining a bosonic formulation of the model introduced by Holstein and Primakoff with probabilistic estimates and operator inequalities.","lang":"eng"}],"intvolume":"       108","status":"public","publication_status":"published","type":"journal_article","date_published":"2014-10-13T00:00:00Z","publisher":"IOP Publishing Ltd.","date_created":"2018-12-11T11:55:18Z","oa_version":"Submitted Version","language":[{"iso":"eng"}],"user_id":"4435EBFC-F248-11E8-B48F-1D18A9856A87","month":"10","title":"Validity of spin-wave theory for the quantum Heisenberg model","issue":"2","publication":"EPL"}
