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, ...
Signatures of symmetry-induced quantum-interference effects observed in above-threshold-ionization spectra of molecules RID A-7617-2010
(American Physical Society, 2001)
Phase-dependent effects in bichromatic high-order harmonic generation RID A-7617-2010
(American Physical Society, 2000)
Channel-closing-induced resonances in the above-threshold ionization plateau RID A-7617-2010

Ramping fermions in optical lattices across a Feshbach resonance RID B-7826-2008

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 ...
Coherent instabilities in a semiconductor laser with fast gain recovery
(American Physical Society, 2007)
We report the observation of a coherent multimode instability in quantum cascade lasers (QCLs), which is driven by the same fundamental mechanism of Rabi oscillations as the elusive Risken-Nummedal-Graham-Haken (RNGH) ...
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 ...
