First Order Phase

Based on the Hamiltonian of the Ising model in a transverse field, we have considered the four-spin interaction which is responsible for the first-order phase transition observed in order-disorder ferroelectrics. Using the method of the retarded Green’s function we have determined the relative polarization, the spin-wave energy, the transverse and longitudinal damping. They are numerically calculated and discussed for different temperature and tunneling frequency values in the cases of first- and second-order phase transitions.

Freeze Out

Abstract We study the stochastic background of gravitational waves which accompany the sudden freeze-out of dark matter triggered by a cosmological first order phase transition that endows dark matter with mass. We consider models that produce the measured dark matter relic abundance via (1) bubble filtering, and (2) inflation and reheating, and show that gravitational waves from these mechanisms are detectable at future interferometers.
