ALP Seminar: Exploring Classical and Quantum Fields in Curved Spacetimes: Lab-Based Investigations into Black Holes and Early Universe Physics

Exploring the dynamics of the early universe and black holes unveils profound insights into the interplay between general relativity and classical/quantum fields. Important phenomena emerge when gravitational and/or field interactions are strong, and/or when quantum effects become prominent. Notable examples include Hawking's proposal on the evaporation of black holes, Penrose's conjecture on the spin-down of rotating black holes, and Kofman's proposal on particle production during preheating. Despite their significance, observing these phenomena directly remains elusive. In this presentation, I will report on recent advancements in investigating these processes in laboratory experiments involving normal and quantum liquids.
