Exit from Inflation with a First-Order Phase Transition and a Gravitational Wave Blast

Authors: Amjad Ashoorioon Preprint number: UUITP-04/15 External Link: ttp://arxiv.org/abs/1502.00556 In double-field inflation, which exploits two scalar fields, one of the fields rolls slowly during inflation whereas the other field is trapped in a meta-stable vacuum. The nucleation rate from the false vacuum to the true one becomes substantial enough that triggers a first order phase transition and ends inflation.
