Optical response properties of hybrid electro-opto-mechanical system interacting with a qubit
Tarun Kumar, Surabhi Yadav, Aranya B Bhattacherjee
We investigate the optical response of a hybrid electro-optomechanical system interacting with a qubit. In our experimentally feasible system, tunable all-optical-switching, double…
Dynamics of an optomechanical resonator containing a Quantum Well induced by periodic modulation of cavity field and external laser beam
Sonam Mahajan, Neha Aggarwal, Tarun Kumar +2
We study in detail the dynamics of a non-stationary system composed of a Quantum Well confined in an optomechanical cavity. This system is investigated with classical and quantized…
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…
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.…
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…
Luttinger liquid in superlattice structures: atomic gases, quantum dots and the classical Ising chain
Aranya B Bhattacherjee, Pradip Jha, Tarun Kumar +1
We study physical properties of a Luttinger liquid in a superlattice which is characterized by alternating two tunneling parameters. Employing the Bosonization approach, we describ…
Entangling two Bose Einstein condensates in a double cavity system
Tarun Kumar, Aranya B Bhattacherjee, ManMohan
We propose a scheme to transfer the quantum state of light fields to the collective density excitations of a Bose Einstein condensate (BEC) in a cavity. This scheme allows to entan…
Dynamics of a movable micro-mirror in a nonlinear optical cavity
Tarun Kumar, Aranya B Bhattacherjee, ManMohan
We consider the dynamics of a movable mirror (cantilever) of a nonlinear optical cavity. We show that a medium with a strong Kerr nonlinearity placed inside a cavity inhi…
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…
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…
Strongly correlated quantum dynamics of multimode light coupled to a two-level atom in a cavity
Tarun Kumar, Aranya B Bhattacherjee, ManMohan
We study a composite multimode light-two-level atom system in a cavity. We show that coupling of the two-level atom to multiple modes of the light destroys the Mott phase of the co…
