Non Degenerate Dual Atomic Parametric Amplifier: Entangled Atomic Fields
Tarun Kumar, Aranya B. Bhattacherjee, Priyanka Verma +2
In this paper, we investigate the dynamics of two coupled quantum degenerate atomic fields (BEC) interacting with two classical optical fields in the nonlinear atom optics regime.…
Amplitude and phase mode in a Bose Einstein condensate
Aranya B. Bhattacherjee
We show that starting from the Heisenberg equations of motion for Bose annihilation and creation operators and using an appropriate transformation, we can split the Bogoliubov mode…
Opto-mechanical effects in superradiant light scattering by Bose-Einstein condensate in a cavity
Aranya B Bhattacherjee
We investigate the effects of a movable mirror (cantilever) of an optical cavity on the superradiant light scattering from a Bose-Einstein condensate (BEC) in an optical lattice. W…
Collapse and revival of oscillations in a parametrically excited Bose-Einstein condensate in combined harmonic and optical lattice trap
Priyanka Verma, Aranya B. Bhattacherjee, ManMohan
In this work, we study parametric resonances in an elongated cigar-shaped BEC in a combined harmonic trap and a time dependent optical lattice by using numerical and analytical tec…
Optomechanical coupling between two optical cavities: cooling of a micro-mirror and parametric normal mode splitting
Tarun Kumar, Aranya B Bhattacherjee, ManMohan
We propose a technique aimed at cooling a harmonically oscillating mirror mechanically coupled to another vibrating mirror to its quantum mechanical ground state. Our method involv…
