Generating Different Types of Quantum Turbulence.
ORAL
Abstract
Cold atomic systems provide a platform for studying quantum turbulence that can be used as a quantum simulator for macroscopic systems like neutron stars. In this talk, I will discuss how experiments can be designed by tuning parameters such as particle number, trapping geometry, and coupling strength, to generate different amounts and types of turbulence for both bosonic and fermionic superfluids across the BEC-BCS crossover. Although superfluids have no fundamental dissipation, these differences can be qualitatively explained, in terms of effective dissipation, after coarse graining. Control over the amount of generated turbulence is crucial for tuning experiments to model superfluids with large turbulent structures.
