CRC 1225 Lunch Seminar: A new experimental platform for dipolar quantum gases towards dynamical studies of exotic phase transitions

Lauriane Chomaz , Physikalisches Institut, UniversiƤt Heidelberg

Dysprosium (Dy), as the most magnetically stable element, offers fascinating prospects for quantum gas research due to its strong anisotropic long-range dipole-dipole interactions competing with tunable short-range contact interactions. These properties have led to the discovery of novel many-body quantum states in recent years, including liquid-like droplets, droplet crystals, and supersolids. With my new group, the Quantum Fluids Group at Heidelberg University, we have designed and implemented a novel compact experimental setup. In this setup we have successfully produced large quantum degenerate gases of bosonic Dy atoms, achieved fine control of the dipolar and contact interactions, and are working towards precise probing of the states. These quantum degenerate gases will later be loaded into tailorable traps and will reach the quasi-two-dimensional regime with the aim of studying quantum many-body physics with competing interactions in this regime, both from a steady-state and a dynamical perspective. In my talk I will present our experimental platform, its special features, the distinct physics at play, and the prospective studies we plan to conduct on the dynamics of these systems near phase transitions featuring the recently discovered exotic states.
