Characterizing Quantum Turbulence in Fermionic Superfluids

Turbulent phenomena abound in nature, but an exact definition of turbulence remains elusive. Several features are key, including vorticity, chaotic behaviour, and energy cascades. Confirmed power-law cascades are often regarded as conclusive evidence for turbulence, but require several decades of scale, and can be difficult to extract from small experiments. In this talk I will discuss strategies for practically characterizing quantum turbulence in fermionic cold atom experiments, validated by simulating turbulent dynamics in the unitary Fermi gas on one of the largest supercomputers in the world with the recently-released W-SLDA density functional theory framework (https://wslda.fizyka.pw.edu.pl).
