Stability of Bloch Oscillations in two coupled Bose-Einstein condensates
Vikash Ranjan, Aranya B Bhattacherjee, Man Mohan
We investigate analytically, the stability of Bloch waves at the boundary of the first Brillouin zone in two coupled Bose-Einstein condensates confined in an optical lattice. Contr…

Quantum Theory of a Bose-Einstein Condensate out of Equilibrium
Aranya B Bhattacherjee, Vikash Ranjan, Man Mohan
We consider the interaction between a single-mode quantized perturbing external field and a Bose-Einstein condensate (BEC) out of equilibrium. The usual Rabi type oscillations betw…
