Description
The critical, universal behaviour of any second-order phase transition gives rise to stochastic anisotropic stresses. These in turn source a stochastic spectrum of gravitational waves. In this talk, I show how to derive the rate of gravitational wave production for second-order phase transitions in the simplest dynamical universality class, Model A, describing a diffusive scalar order parameter. The result is a broken power law which grows towards high frequencies.
