Hidden vortices and Feynman rule in Bose-Einstein condensates with density-dependent gauge potential
Ishfaq Ahmad Bhat, Bishwajyoti Dey
In this article, we numerically investigate the vortex nucleation in a Bose-Einstein condensate trapped in a double-well potential and subjected to a density-dependent gauge potent…
Vortex nucleation in rotating Bose-Einstein condensates with density-dependent gauge potential
Ishfaq Ahmad Bhat, Thudiyangal Mithun, Bishwajyoti Dey
We study numerically the vortex dynamics and vortex-lattice formation in a rotating density-dependent Bose-Einstein condensate (BEC), characterized by the presence of nonlinear rot…
Impurity induced Modulational instability in Bose-Einstein condensates
Ishfaq Ahmad Bhat, Bishwajyoti Dey
By means of linear stability analysis (LSA) and direct numerical simulations of the coupled Gross-Pitaevskii(GP)equations, we address the impurity induced modulational instability…
Modulational instability and soliton generation in chiral Bose-Einstein condensates with zero-energy nonlinearity
Ishfaq Ahmad Bhat, S. Sivaprakasam, Boris A. Malomed
By means of analytical and numerical methods, we address the modulational instability (MI) in chiral condensates governed by the Gross-Pitaevskiiequation including the current nonl…
Modulational instability in binary spin-orbit-coupled Bose-Einstein condensates
Ishfaq Ahmad Bhat, T. Mithun, B. A. Malomed +1
We study modulation instability (MI) of flat states in two-component spin-orbit-coupled (SOC) Bose-Einstein condensates (BECs) in the framework of coupled Gross-Pitaevskii equation…
Continuous-wave solutions and modulational instability in spinor condensates of positronium
Ishfaq Ahmad Bhat, Thudiyangal Mithun, B. A. Malomed +1
We obtain general continuous-wave (CW)\ solutions in the model of a spinor positronium condensate in the absence of magnetic field. The CW solutions with both in-phase () and…
