Selective entanglement in a two-mode optomechanical system
Neha Aggarwal, Kamanasish Debnath, Sonam Mahajan +2
We analyze an optomechanical system formed by a mechanical mode and the two optical modes of an optomechanical cavity for the realization of a strongly quantum correlated three-mod…
Excitations of optomechanically driven Bose-Einstein condensates in a cavity: photodetection measurements
Neha Aggarwal, Sonam Mahajan, Aranya B Bhatttacherjee +1
We present a detailed study to analyse the Dicke quantum phase transition within the thermodynamic limit for an optomechanically driven Bose-Einstein condensates in a cavity. The p…
Influence of periodically modulated cavity field on the generation of atomic-squeezed states
Neha Aggarwal, Aranya B Bhattacherjee, Arup Banerjee +1
We investigate the influence of periodically time-modulated cavity frequency on the generation of atomic squeezed states for a collection of N two-level atoms confined in a non-sta…
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.…
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…
Probing superfluidity of periodically trapped ultracold atoms in a cavity by transmission spectroscopy
Aranya B. Bhattacherjee, Tarun Kumar, ManMohan
We study a system of periodic Bose condensed atoms coupled to cavity photons using the input-output formalism. We show that the cavity will either act as a through pass Lorentzian…
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…
