Detection of Weak Force using a Bose-Einstein Condensate
Sonam Mahajan, Tarun Kumar, Aranya B Bhattacherjee +1
We investigate the possibility of detecting a weak coherent force by means of a hybrid optomechanical quantum device formed by a Bose Einstein Condensate (BEC) confined in a high q…

Two-photon nonlinear spectroscopy of periodically trapped ultracold atoms in a cavity
Tarun Kumar, Aranya B Bhattacherjee, ManMohan
We study the transmission spectra of a Bose Einstein condensate confined in an optical lattice interacting with two modes of a cavity via nonlinear two-photon transition. In partic…

Quantum phases of light coupled to a periodic Bose-Einstein condensate in a cavity
Aranya B. Bhattacherjee, ManMohan
We study a composite photon-Bose condensed atoms (BEC) system in an optical lattice confined in a cavity. We show that the system is able to produce an effective photon-photon repu…
