Long Talk (20 mins) Gravity


Ansh Gupta (King's College London)


Vortices in quantum fluids, such as Bose-Einstein condensates, have discrete charges associated with their circulations. Higher charged quantum vortices have dynamical instabilities which arise from bound states inside the vortex core, resulting in vortex splitting. These multiply charged quantum vortices can be stabilised by adding a second component to the condensate. This talk will introduce this stabilisation mechanism, and explore some of its novel consequences such as orbit reversal and vortex recombination. This has potential applications in experiments looking to probe black holes via analogue gravity.
