Applied Mathematics Seminars: Quantum fluids flex their muscles

7 December 2018 15:00 in CM301

Vortices are the muscles of fluid motion. In quantum fluids, such as superfluid Helium and ultracold gases, these muscles are particularly simple, having fixed core size and circulation. This, along with the absence of viscosity, makes these fluids a highly idealised system to study vortex dynamics and turbulence. Moreover, recent experimental advances now enable precise, real-time monitoring of individual quantum vortices.

Here I will discuss our work in understanding the dynamics of quantum vortices. This will range from their microscopic behaviour, such as vortex nucleation and reconnection events between two vortices, to their macroscopic domain of collective structures and quantum turbulence. Throughout, I will relate our findings to the latest experiments and analogs in classical fluids. If time permits, I will also discuss an even more exotic fluid - the quantum ferrofluid.
