Description
We consider phase transitions with symmetry restoration, where particles
become massless inside the bubbles, and the leading order friction is
negative, causing the expanding bubble walls to accelerate, contrary to
standard phase transitions. We study the next to leading order
corrections arising from transition radiation in this case, which are
known to prevent runaway behavior in standard phase transitions. We find
that the friction component changes from negative to positive friction
as the wall boost factor increases to moderate values, so that runaway
behavior occurs for longer compared to standard transitions but
terminates at intermediate regimes.
