Analogue simulators for fundamental physics: From quantum to classical (and back)

Abstract

Quantum and classical fluids, and their non-equilibrium evolution, present an ideal platform to study fundamental processes of (quantum) field theory in controlled laboratory systems. Here, I present recent results and future prospects for analogue quantum simulators based on effective field theory descriptions in linear and non-linear regimes. I will discuss analogue quantum simulators utilising cold atom quantum many body systems in the context of analogue gravity, cosmology, and detector physics as well as an analogue for preheating dynamics after cosmic inflation in classical parametrically driven two fluid systems.
