Motion of vortices in inhomogeneous Bose-Einstein condensates
Andrew J. Groszek, David M. Paganin, Kristian Helmerson +1
We derive a general and exact equation of motion for a quantised vortex in an inhomogeneous two-dimensional Bose-Einstein condensate. This equation expresses the velocity of a vort…
Collision dynamics of two-dimensional non-Abelian vortices
T. Mawson, T. C. Petersen, T. Simula
We study computationally the collision dynamics of vortices in a two-dimensional spin-2 Bose-Einstein condensate. In contrast to Abelian vortex pairs, which annihilate or pass thro…
Vortex Mass in a Superfluid
Tapio Simula
We consider the inertial mass of a vortex in a superfluid. We obtain a vortex mass that is well defined and is determined microscopically and self-consistently by the elementary ex…
Vortex Thermometry for Turbulent Two-Dimensional Fluids
Andrew J. Groszek, Matthew J. Davis, David M. Paganin +2
We introduce a new method of statistical analysis to characterise the dynamics of turbulent fluids in two dimensions. We establish that, in equilibrium, the vortex distributions ca…
