Effects of the cosmological expansion on the bubble nucleation rate for relativistic first-order phase transitions

arXiv:0804.1045 · doi:10.1103/PhysRevD.78.063533

Abstract

I calculate the first corrections to the dynamical pre-exponential factor of the bubble nucleation rate for a relativistic first-order phase transition in an expanding cosmological background by estimating the effects of the Hubble expansion rate on the critical bubbles of Langer's statistical theory of metastability. I also comment on possible applications and problems that arise when one considers the field theoretical extensions of these results (the Coleman-De Luccia and Hawking-Moss instantons and decay rates).
