Abstract
This dissertation explores quantum turbulence in the context of both bosonic and fermionic superfluids. After developing the mathematical and theoretical frameworks, I present the results from three projects. The first shows that important features of 3D turbulence can be captured by a 2D axially symmetric model. By comparing superfluid dynamics with classical hydrodynamics, we calibrate a model for the effective viscosity that measures the underlying quantum turbulence. The second explores fermionic turbulence in one of the largest simulations performed to date. The third looks at the linear and non-linear response of fermionic superfluid in a box potential. This work combines all the aspects of turbulence in a superfluid: controlled generation, verification, measurement and prediction.
