Description
Sampling methods based on the density of states provide a framework for determining properties of first-order phase transitions of gauge theories from first principles. These transitions are physically interesting, e.g. in the context of predicting a stochastic gravitational wave signal from early universe phase transitions. I will present results for $Sp(4)$ Yang-Mills theory around its first-order thermal phase transition by reconstructing the density of states via the logarithmic linear relaxation (LLR) algorithm. I will show results on different space and time extents, as well as aspect ratios, and estimate discretisation artifacts. We see clear signatures of the first-order transition and determine the critical coupling, the specific heat and set bounds on the surface tension.
