Description
First-order phase transitions play a pivotal role in many models of particle physics and the early Universe, and are a key target of current and future gravitational-wave observatories. However, we lack a satisfying theoretical understanding of this process, with existing approaches working only in imaginary (Euclidean) time, and relying on assumptions that have yet to be empirically tested. A promising route forward is to use cold-atom systems which undergo phase transitions that are analogous to those in the early Universe. In this talk, I will present recent theoretical work to understand this analogy using semiclassical lattice simulations, and will discuss possibilities and challenges for realising these analogues in the laboratory.
