Description:
Author(s): Yulia E. Shchadilova, Fabian Grusdt, Alexey N. Rubtsov, and Eugene Demler We propose a class of variational Gaussian wave functions to describe Fröhlich polarons at finite momenta. Our wave functions give polaron energies that are in excellent agreement with the existing Monte Carlo results for a broad range of interactions. We calculate the effective mass of polarons and… [Phys. Rev. A 93, 043606] Published Thu Apr 07, 2016
