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…

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…

Impurities induced vortex lattice melting and turbulence in rotating Bose-Einstein condensates
Rony Boral, Swarup K. Sarkar, Paulsamy Muruganandam +1
We investigate the impact of various impurities on rotating Bose-Einstein condensates confined within two-dimensional harmonic and optical lattice potentials. Without impurities, t…
