Stability of quantised vortices in two-component condensates
Sam Patrick, Ansh Gupta, Ruth Gregory +1
Multiply quantised vortices (MQVs) within single component Bose-Einstein condensates are unstable and decay rapidly. We show that MQVs can be stabilised by adding a small number of…
Quantum vortex instability and black hole superradiance
Sam Patrick, August Geelmuyden, Sebastian Erne +2
Vortices and black holes set the scene for many interesting dynamical processes in physics. Here, we study the dynamical instability of quantised vortices and rotational superradia…
Origin and evolution of the multiply-quantised vortex instability
Sam Patrick, August Geelmuyden, Sebastian Erne +2
We show that the dynamical instability of quantum vortices with more than a single quantum of angular momentum results from a superradiant bound state inside the vortex core. Our c…
