Abstract
In this dissertation, I develop theoretical and computational techniques to analyze quantum superfluid dynamics.
In particular, I model several different types of BEC including superfluid mixtures and SOC BEC with higher-order dispersion that lead to interesting physics like turbulence, and negative mass.
We use these models to explain cold atom experiments where the dispersion is highly tunable.
Realistic experiments require large volumes so I implement efficient approximations such as effective 1D tube and axially symmetric simulations, and moving and expanding reference frames that keep the simulation size small.
These techniques are used to model the interaction between shock waves and vortices, and NASA's superfluid experiments on the ISS where a BEC is transported a large distance.
