Our main result is the derivation of the Bogoliubov dynamics and higher-order corrections. More precisely, we prove the convergence of the approximate wave function to the many-body wave function in norm, with a convergence rate proportional to the number of corrections taken into account in the approximation. We prove an analogous result for the unitary propagator. As an application, we derive a simple system of partial differential equations describing the time evolution of the first- and second-order approximations to the one-particle reduced density matrices of the particles and the quantum field, respectively.","lang":"eng"}],"isi":1,"day":"09","main_file_link":[{"open_access":"1","url":" https://doi.org/10.48550/arXiv.2110.00458"}],"publisher":"World Scientific Publishing","type":"journal_article","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87"}
