Quantum Fluids: Investigating Ultracold Gases

This lecture explores the investigation of quantum matter with ultracold gases, focusing on the dilute assembly of particles and the manifestation of quantum physics macroscopically. It delves into ultracold gas experiments, the advantages of the atomic-gas platform, and the study of many-body and few-body quantum phenomena. The lecture also covers the potential of atoms with dipole-dipole interactions and the quest for supersolidity in quantum gases. The instructor presents insights on the physical impact of momentum-dependent interactions, the stabilization of dipolar gases from fluctuations, and the dynamics in interaction quenches. Additionally, the lecture discusses the experimental probing of supersolidity and the theoretical understanding of quantum-stabilization mechanisms.
