Title: Probability of passing through a parabolic barrier and thermal decay rate: Case of linear coupling both in momentum and in coordinate

Abstract

With the quantum diffusion approach, the probability of passing through the parabolic barrier and the quasistationary thermal decay rate from a metastable state are examined in the limit of linear coupling both in momentum and in coordinate between a collective subsystem and the environment. An increase of passing probability with friction coefficient is demonstrated to occur at subbarrier energies.
