Abstract:
In this seminar I will discuss methods for extracting, testing, and designing effective field theory descriptions for continuous (quantum) field theory simulators. After introducing general concepts for the preparation, design, and detection of effective field theories in cold atom systems, I will present our latest results on the floquet engineered sine-Gordon model, emerging as the effective quantum field theory description of two tunnel-coupled quantum wires, and on parametrically driven classical two-fluid interfaces as analogue simulators for the onset of nonlinearities in preheating dynamics. Special focus will be on factorization properties of higher-order correlations as sensitive probes for nonlinear dynamics in strongly correlated field theories which opens a window in the experimental extraction of emergent field theory descriptions for complex many-body systems.
