Quadrature entanglement and photon-number correlations accompanied by phase-locking
H. H. Adamyan, N. H. Adamyan, S. B. Manvelyan +1
We investigate quantum properties of phase-locked light beams generated in a nondegenerate optical parametric oscillator (NOPO) with an intracavity waveplate. This investigation co…
Laser spectroscopy with nanometric gas cells : distance dependence of atom-surface interaction and collisions under confinement
Ismahène Hamdi, Petko Todorov, Alexander Yarovitski +11
The high sensitivity of Laser Spectroscopy has made possible the exploration of atomic resonances in newly designed "nanometric" gas cells, whose local thickness varies from 20nm t…
Entanglement and criticality in translational invariant harmonic lattice systems with finite-range interactions
R. G. Unanyan, M. Fleischhauer
We discuss the relation between entanglement and criticality in translationally invariant harmonic lattice systems with non-randon, finite-range interactions. We show that the crit…
An Alkali-Vapor Cell with Metal Coated Windows for Efficient Application of an Electric Field
David Sarkisyan, A. S. Sarkisyan, Jocelyne Guéna +2
We describe the implementation of a cylindrical T-shaped alkali-vapor cell for laser spectroscopy in the presence of a longitudinal electric field. The two windows are used as two…
Influence of relaxation on propagation, storage and retrieving of light pulses in electromagnetically induced transparency medium
Gor Nikoghosyan, Gayane Grigoryan
By solving the self-consistent system of Maxwell and density matrix equations to the first order with respect to nonadiabaticity, we obtain an analytical solution for the probe pul…
Quantum Theory for Generation of Nonclassical Photon Pairs by a Medium with Coherent Atomic Memory
Narek Sisakyan, Yuri Malakyan
We present a fully quantum mechanical treatment of recent experiments on creation of collective quantum memory and generation of non-classically correlated photon pairs from an ato…
