Rabi-induced localization and resonant delocalization of a binary condensate in a spin-asymmetric quasiperiodic potential
Swarup K. Sarkar, Sh. Mardonov, E. Ya. Sherman +1
We theoretically investigate the ground state and dynamics of a Rabi-coupled pseudospin-1/2 Bose-Einstein condensate, where only one spin component is subjected to an external pote…
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…
Spin-dependent localization of spin-orbit and Rabi-coupled Bose-Einstein condensates in a random potential
Swarup K. Sarkar, Sh. Mardonov, E. Ya. Sherman +2
We investigate the effect of the spin-orbit (SO) and Rabi couplings on the localization of the spin-1/2 condensate trapped in a one-dimensional random potential. Our studies reveal…
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…
