Particle creation in a toroidal universe
arXiv:1207.6230 · doi:10.1103/PhysRevD.86.083519
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.
