Particle creation in a toroidal universe

Published 26 Jul 2012 in hep-th and astro-ph.CO | (1207.6230v1)

Abstract: We calculate the particle production rate in an expanding universe with a three-torus topology. We discuss also the complete evolution of the size of such a universe. The energy density of particles created through the nonzero modes is computed for selected masses. The unique contribution of the zero mode and its properties are also analyzed.
