Neutral vortex necklace in a trapped planar superfluid
M. M. Cawte, M. T. Reeves, A. S. Bradley
We study quantum vortex states consisting of a ring of vortices with alternating sign, in a homogeneous superfluid confined to a circular domain. We find an exact stationary soluti…

Snell's Law for a vortex dipole in a Bose-Einstein condensate
Michael M. Cawte, Xiaoquan Yu, Brian P. Anderson +1
A quantum vortex dipole, comprised of a closely bound pair of vortices of equal strength with opposite circulation, is a spatially localized travelling excitation of a planar super…
