Description

The study of cosmological first order phase transitions, and the associated gravitational wave signal, has seen growing interest in recent years, driven by the prospects of detection with next-generation ground- and space-based interferometers.
Here, I present PT2GWFinder, a Mathematica package designed to compute phase transition parameters and the gravitational wave power spectrum for an arbitrary scalar theory exhibiting a first-order phase transition in a single direction.
