Quantum Turbulence


Quantum turbulence is distinct from turbulence in ordinary fluids due to the absence of viscosity and the discrete nature of the vorticity. We study the fundamental properties of turbulence across superfluid liquid helium (both bosonic 4He and fermionic 3He) and atomic condensates. Topics include the generation of turbulence, the statistical properties of the flow, analogies to classical turbulence, the diffusion of quantised vorticity, the theory behind methods of visualizing turbulence, and the interaction between vortex lines and boundaries.
We are also interested in investigating two-dimensional quantum turbulence; particularly the properties of cylinder wakes and the transition to turbulence, and the emergence of quasi-classical inverse energy and forward enstrophy cascades.
