Cold-atom analogues for vacuum decay


False vacuum decay plays a pivotal role in many models of particle physics and the early Universe. 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. In this talk, I will describe ongoing efforts to simulate vacuum decay in tabletop experiments, using ultra-cold atomic condensates which mimic the behaviour of relativistic quantum fields. I will present recent theoretical work to understand this analogy using semiclassical lattice simulations, and will discuss opportunities and challenges for realising these analogues in the laboratory.

Simulating the cosmic web and its galaxies



Galaxies are not distributed randomly in our Universe, but trace an intricate “cosmic web” with galaxy clusters and filaments as its most prominent elements. Observations tell us that these different environments have a strong impact on the galaxies within them, but our theoretical understanding of this co-evolution remains patchy. In this seminar, I illustrate how modern hydrodynamic simulations can help fill this gap and provide physical insight into the processes that shape clusters, filaments, and their galaxies. I will highlight progress on three central questions: Why have so many galaxies in clusters quenched their star formation? What is the origin of the faint “intra-cluster light” that permeates galaxy clusters? And how much do filaments really affect the evolution of galaxies? To end, I will discuss how new tools will soon enable another leap forward in our modelling and understanding of the cosmic web.
