Measuring finite-range phase coherence in an optical lattice using Talbot interferometry
Autor: Bodhaditya Santra, Christian Baals, Ralf Labouvie, Aranya B. Bhattacherjee, Axel Pelster, Herwig Ott
Publikováno v: Nature Communications, Vol 8, Iss 1, Pp 1-8 (2017)
Quantum gas experiments are useful to study non-equilibrium many-body dynamics. Here, the authors demonstrate how the Talbot effect can be used to measure the spreading of phase coherence of ultracold atoms in an optical lattice.

Influence of Virtual Photon Process on the Generation of Squeezed Light from Atoms in an Optical Cavity
Autor: Aranya B. Bhattacherjee
Publikováno v: Atoms, Vol 3, Iss 3, Pp 339-347 (2015)
We show that a collection of two-level atoms in an optical cavity beyond the rotating wave approximation and in the dispersive-adiabatic and non-dispersive adiabatic regime constitutes a nonlinear medium and is capable of generating squeezed state of

Strong squeezing and robust entanglement in a second-order coupled optomechanical cavity assisted by a Kerr nonlinear medium
Autor: Sonam Mahajan, Neha Aggarwal, Aranya B. Bhattacherjee
Publikováno v: Journal of Nonlinear Optical Physics & Materials.
We investigate theoretically an optomechanical system composed of an optical mode and a mechanical mode interacting through first-order coupling and second-order coupling in the presence of a Kerr nonlinear medium. We study how the nonlinearities (se
