Resonant enhancement of high-order optical nonlinearities based on atomic coherence RID A-1272-2007
(American Physical Society, 2002)
We show that the effect of coherent population trapping may result in resonant enhancement of chi((5)) or higher-order nonlinearities. The enhancement is accompanied by suppression of the other linear and nonlinear ...
Hanbury Brown-Twiss effect and thermal light ghost imaging: A unified approach
(American Physical Society, 2009)
We compare the Hanbury Brown-Twiss (HBT) and the thermal light ghost imaging schemes in both near and far fields. Both effects arise as a result of the intensity fluctuations of the thermal light and we find that the ...
Two-time intensity correlation in a driven three-level system
(American Physical Society, 1996)
We examine the various two-time fluorescence intensity correlations emitted by a driven three-level atom in a cascade configuration. For a strongly driven atom, the two intensity autocorrelation functions, one from the ...
Single atom as a macroscopic entanglement source
(American Physical Society, 2006)
We discuss the generation of a macroscopic entangled state in a single atom cavity-QED system. The three-level atom in a cascade configuration interacts dispersively with two classical coherent fields inside a doubly ...
Gaussian-state entanglement in a quantum beat laser
(American Physical Society, 2011)
Recently quantum beat lasers have been considered as a source of entangled radiation [S. Qamar, F. Ghafoor, M. Hillery, and M. S. Zubairy, Phys. Rev. A 77, 062308 (2008)]. We investigate and quantify the entanglement of ...
K-Shell-Hole Production, Multiple-Hole Production, Charge-Transfer, and Antisymmetry
(American Physical Society, 1980)
Polarization and Pressure-Dependence of 2p-1s Transitions in He-Like and Li-Like Neon Recoil Ions
(American Physical Society, 1987)
Binding Effects in High-Energy Scattering Applied to K-Shell Ionization
(American Physical Society, 1975)
Condensation of N bosons. II. Nonequilibrium analysis of an ideal Bose gas and the laser phase-transition analogy
(American Physical Society, 2000)
A nonequilibrium approach to the dynamics and statistics of the condensate of an ideal N-atom Bose gas cooling via interaction with a thermal reservoir using the canonical ensemble is developed. We derive simple analytical ...
Multimode regimes in quantum cascade lasers: From coherent instabilities to spatial hole burning RID B-8648-2009
(American Physical Society, 2008)
A theoretical and experimental study of multimode operation regimes in quantum cascade lasers (QCLs) is presented. It is shown that the fast gain recovery of QCLs promotes two multimode regimes: One is spatial hole burning ...
