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…
Decay of two-dimensional quantum turbulence in binary Bose-Einstein condensates
Mithun Thudiyangal, Kenichi Kasamatsu, Bishwajyoti Dey +1
We study two-dimensional quantum turbulence in miscible binary Bose-Einstein condensates in either a harmonic trap or a steep-wall trap through the numerical simulations of the Gro…
Quantum Vortex States in Bose Hubbard Model With Rotation
Mukesh P. Khanore, Bishwajyoti Dey
We study quantum vortex states of strongly interacting bosons in a two-dimensional rotating optical lattice. The system is modeled by Bose-Hubbard Hamiltonian with rotation. We con…
Stabilization of trapless dipolar Bose-Einstein condensates by temporal modulation of the contact interaction
S. Sabari, Bishwajyoti Dey
We theoretically study the stability of a trapless dipolar Bose-Einstein condensate (BEC) with temporal modulation of short-range contact interaction. For this aim, through both an…
Study of implosion in an attractive Bose-Einstein condensate
S. Sabari, A. Choudhuri, K. Porsezian +1
By solving the Gross-Pitaevskii equation analytically and numerically, we reexamine the implosion phenomena that occur beyond the critical value of the number of atoms of an attrac…
