One-atom correlated-emission laser RID C-6638-2008
(American Physical Society, 2008)
We study a four-level double-Lambda atomic configuration working as a two photon linear amplifier where two atomic transitions independently interact with cavity mode, while the other transitions are driven by a strong ...
Goos-Hänchen Shifts of Partially Coherent Light Fields
(Physical Review Letters, 2013)
Correlation of photon pairs from the double Raman amplifier: Generalized analytical quantum Langevin theory
(American Physical Society, 2007)
We present a largely analytical theory for two-photon correlations G((2)) between Stokes (s) and anti-Stokes (a) photon pairs from an extended medium (amplifier) composed of double-Lambda atoms in counterpropagating geometry. ...
Dynamical theory of single-photon transport in a one-dimensional waveguide coupled to identical and nonidentical emitters
(Physical Review A - Atomic, Molecular, and Optical Physics, 2016)
Quantum state measurement using phase-sensitive amplification in a driven three-level atomic system
(American Physical Society, 2001)
Phase-sensitive amplification in a three-level atomic system exhibits interesting features. For example, in the zero-detuning limit and for sufficiently strong driving field, this system becomes an ideal parametric amplifier, ...
Quantum theory of a micromaser operating on the atomic scattering from a resonant standing wave
(American Physical Society, 2001)
We study the amplification of a resonant standing-wave light field due to the interaction with a beam of monovelocity two-level atoms moving in the Raman-Nath regime and in the Bragg regime. The atomic density is low so ...
Improving engine efficiency by extracting laser energy from hot exhaust gas RID A-1272-2007
(American Physical Society, 2003)
We show that it is possible to improve the efficiency of a classical Otto-cycle heat engine by adding a high-Q microwave cavity and a laser system that can extract coherent laser energy from thermally excited "exhaust" ...
Localization of atomic ensembles via superfluorescence RID B-9093-2009 RID A-5077-2009
(American Physical Society, 2007)
The subwavelength localization of an ensemble of atoms concentrated to a small volume in space is investigated. The localization relies on the interaction of the ensemble with a standing wave laser field. The light scattered ...
Cavity-QED-based quantum phase gate
(American Physical Society, 2003)
We describe a quantum phase gate in which the two qubits are represented by the photons in the two modes of the cavity field. The gate is implemented by passing a three-level atom in a cascade configuration through the ...
Tunable phase control for subluminal to superluminal light propagation
(American Physical Society, 2004)
We demonstrate tunable control of the group velocity of a weak probe pulse from subluminal to superluminal. The model is an extended Lambda-type system with two extra control fields and an extra energy level. Phase variation ...
