Dynamical Casimir effect from fermions in an oscillating bag in 1+1 dimensions

Abstract

We evaluate dissipative effects for a system consisting of a massive Dirac field confined between two walls, one of them oscillating, in 1+1 dimensions. In the model that we consider, a dimensionless parameter characterizing each wall is tuned so that bag-boundary conditions are attained for a particular value. We present explicit results for the probability of creating a fermion pair, and relate the total probability to the imaginary part of the effective action.
