We are currently setting up a new (2+1) dimensional simulator to study black hole dynamics of rotating black hole analogues. This work is building up on the pioneering work on black hole superradiance and ring-down based on surface waves interacting with stationary draining vortex flows. In simple terms, we will implement a quantum version of our classical experiment in superfluid 4He. Superfluid 4He exhibits macroscopic quantum coherence which leads to a fluid with zero viscosity, high thermal conductivity and quantised vortices. Consequently, it is an ideal system for such a quantum simulator, as it allows mapping the dynamics of rotating black holes from macro- to nanoscales, with the additional feature of quantised angular momentum. To realise this, we needed a new purpose built facility. This activity is part of the UK-wide network initiative on Quantum Simulators for Fundamental Physics, one of the seven consortia funded through the UK Research and Innovation Quantum Technologies for Fundamental Physics call.
