Particle creation in cosmological space-time by a time-dependent electric field
In this work, we calculate the particle creation density in a cosmological anisotropic Bianchi I universe, by solving the Klein-Gordon and Dirac equations in the presence of a time-dependent electric field using the semi-classical method. We show that the particles distribution becomes thermal under the influence of the electric field when the electric interaction proportional to the Ricci scalar of curved space-time
