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.

Special requests It would be great if this talk takes place after the one from David Mason
