Emergence of giant vortices under nonlinear rotation with attractive interactions in a toroidal condensate
Rony Boral, Swarup K. Sarkar, Matthew Edmonds +2
We numerically investigate the effects of a density-dependent gauge potential which induces nonlinear rotation on a Bose-Einstein condensate confined in a toroidal trapping geometr…
Polar core vortex dynamics in disc-trapped homogeneous spin-1 Bose-Einstein condensates
Matthew Edmonds, Lewis A. Williamson, Matthew J. Davis
We study the dynamics of polar core vortices in the easy plane phase of an atomic spin-1 Bose-Einstein condensate confined in a two-dimensional disc potential. A single vortex move…
Excitation spectrum of vortex-lattice modes in a rotating condensate with a density-dependent gauge potential
Rony Boral, Swarup K. Sarkar, Matthew Edmonds +2
We investigate the collective excitation spectrum of a quasi-2D Bose-Einstein condensate trapped in a harmonic confinement with nonlinear rotation induced by a density-dependent ga…
Quantum droplets in a beyond-mean-field density-dependent gauge theory
Matthew Edmonds, Patrik Ãhberg
The beyond-mean-field corrections appropriate to a bosonic many-body system experiencing a density-dependent gauge potential are derived, and from this the dimensional hierarchy of…
