Description
Many models of composite dark matter feature a first-order confinement transition in the early universe, which would produce a stochastic background of gravitational waves that will be searched for by future gravitational-wave observatories. I will present work in progress using lattice field theory to predict the properties of such first-order transitions and the resulting spectrum of gravitational waves. Targeting both the thermal as well as the bulk phase transitions of SU(N) Yang-Mills theories, this work employs the Logarithmic Linear Relaxation (LLR) density of states algorithm to avoid long autocorrelations.
