Description

Inverse phase transitions in which tunneling proceeds into a finite-temperature vacuum away from the zero-temperature vacuum exhibit different fluid profiles than usual (direct) transitions. We investigate the effect this has on the sound wave contribution to the stochastic gravitational wave background generated in such transitions.
