Superfluid vortex dynamics on an ellipsoid and other surfaces of revolution
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 flow forbids distributed vorticity. A conformal transformation from the surface to the complex plane allows us to use fam...

| Sumario: | 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 flow forbids distributed vorticity. A conformal transformation from the surface to the complex plane allows us to use familiar formalism to describe the motion of the quantized vortices and to find the total energy. The simplest case is a vortex dipole with unit vortex charges on an axisymmetric ellipsoid. We study two special symmetric vortex-dipole configurations along with a general asymmetric one. |
