Quantifying Turbulence in Fermionic Superfluids

ORAL

Abstract

We analyze the largest fermionic cold atom simulations where turbulence is imprinted externally in the form of a vortex lattice along all 3 dimensions. Although numerically the vortex length can be calculated, experimentally measuring it is extremely difficult. To address this, we use a shock wave as a probe and extract the superfluid transport properties. The goal being that extracting a hydrodynamic effective viscosity would give a good quantitative model for turbulence. A few methods are explored for identifying turbulence as well.
