Conformal maps and superfluid vortex dynamics on curved and bounded surfaces: the case of an elliptical boundary
Matteo Caldara, Andrea Richaud, Pietro Massignan +1
Recent advances in cold-atom platforms have made real-time dynamics accessible, renewing interest in the motion of superfluid vortices in two-dimensional domains. Here we show that…
Dynamics of a massive superfluid vortex in confining potentials
Andrea Richaud, Pietro Massignan, Vittorio Penna +1
We study the motion of a superfluid vortex in condensates having different background density profiles, ranging from parabolic to uniform. The resulting effective point-vortex mode…
Superfluid vortex dynamics on an ellipsoid and other surfaces of revolution
Mônica A. Caracanhas, Pietro Massignan, Alexander L. Fetter
We study the dynamics of quantized superfluid vortices on axisymmetric compact surfaces with no holes, where the total vortex charge must vanish and the condition of irrotational f…
Superfluid vortex dynamics on a spherical film
Sálvio Jacob Bereta, Mônica A. Caracanhas, Alexander L. Fetter
Motivated by ongoing experimental efforts to make closed Bose-Einstein condensate (BEC) shells in microgravity environments, this work studies the energy and dynamics of singly qua…
Dynamics of massive point vortices in binary mixture of Bose-Einstein condensates
Andrea Richaud, Vittorio Penna, Alexander L. Fetter
We study the massive point-vortex model introduced in Ref. [Phys. Rev. A 101, 013630 (2020)], which describes two-dimensional point vortices of one species that have small cores of…
Superfluid vortex dynamics on a torus and other toroidal surfaces of revolution
Nils-Eric Guenther, Pietro Massignan, Alexander L. Fetter
The superfluid flow velocity is proportional to the gradient of the phase of the superfluid order parameter, leading to the quantization of circulation around a vortex core. In thi…
