Compressible quantum turbulence with ultra-cold atoms.*

Ultracold atoms provide an experimental platform for studying compressible quantum turbulence with broad applications as quantum simulators of other systems including neutron stars. As first suggested by Feynman, quantized vortices play a key role in quantum turbulence, providing a microscopic mechanism for energy transfer across different scales.  Theoretical descriptions of quantum turbulence tend to focus on properties of these vortices, but this description is complicated when the fluid is compressible as there are multiple ways to partition the energy between rotational and compressional flow.  In this talk I will discuss some aspects of compressible quantum turbulence, and showcase results of large-scale simulations including turbulence in rotating and non-rotating systems.
