Landau–Pekar equations and quantum fluctuations for the dynamics of a strongly coupled polaron
We consider the Fröhlich Hamiltonian with large coupling constant α.For initial data of Pekar product form with coherent phonon field and with the electron minimizing the corresponding energy, we provide a norm approximation of the evolution, valid up to times of order α 2 .The approximation is given in terms …
