Description
Building upon the recently proposed concept of inverse FOPT, we investigate their GW signatures. We outline how these transitions differ thermodynamically and hydrodynamically from standard ones and analyse the resulting GW emission from the plasma.
Adopting the bag equation of state as a minimal setup, we compute self-similar fluid profiles over a range of wall velocities and transition strengths. We evaluate the GW spectrum from sound waves via the Sound Shell Model, and compare it to analytic fits.
This analysis allows us to probe whether inverse transitions produce distinguishable spectral features, assess their observability with future detectors like LISA.
