The effective mass problem for the Landau–Pekar equations
The effective mass problem for the Landau–Pekar equations
We provide a definition of the effective mass for the classical polaron described by the Landau-Pekar equations. It is based on a novel variational principle, minimizing the energy functional over states with given (initial) velocity. The resulting formula for the polaron's effective mass agrees with the prediction by Landau and …
