Title: Rotating black hole analogues in quantum fluids

Abstract: What happens if a black hole has quantised angular momentum? One way to answer this question is by studying an analogue model; a system with a well-defined quantum theory which mimics certain black hole scattering processes. I will describe such a model, a draining vortex in superfluid helium, which has recently been built at the University of Nottingham. I will then summarise recent theoretical and experimental progress. In particular, it turns out a well-known instability in quantum fluids is related to rotational superradiant scattering, the mechanism by which black holes shed their angular momentum.
