Josephson Dynamics of a Bose-Einstein Condensate in an Accelerated Double Well Potential
Aranya B Bhattacherjee
Motivated by recent experiment on Bloch Oscillation of Bose-Einstein condensates (BEC) in accelerated optical lattices, we consider the Josephson dynamics of a BEC in an accelerate…
Dynamics of Coupled Topological - Collective Modes of a Bose-Einstein Condensate
Aranya B Bhattacherjee
We develop the theory of the resonant formation of coupled topological-collective coherent modes in the presence of a quantized trap and classical external field. The coupling betw…
Quantum theory of vortex lattice state in a rotating Bose-Einstein condensate
Aranya B. Bhattacherjee
We study system of large number of singly quantized vortices in a rotating Bose-Einstein condensate. Analogous to the Meissner effect in superconductors, we show that the vector po…
Vortex flux and Berry phase in a Bose-Einstein condensate confined in a toroidal trap
Aranya B Bhattacherjee
We study a system of large number of singly quantized vortices in a BEC confined in a rotating toroidal geometry. Analogous to the Meissner effect in supercomputers, we show that t…
