Spectroscopic measurement of an atomic wave function
(American Physical Society, 2003)
We present a simple spectroscopic method based on Autler-Townes spectroscopy to determine the center-of-mass atomic wave function. The detection of spontaneously emitted photons from a three-level atom, in which two upper ...
Reconstruction of a multimode entangled state using a two-photon phase-sensitive linear amplifier
(American Physical Society, 2003)
We propose a model for the measurement of an arbitrary multimode entangled state of the cavity field using two-photon correlated emission laser. We consider two cases: (a) The modes have different frequencies and are ...
Quenching of spontaneous emission through interference of incoherent pump processes
(American Physical Society, 2003)
We investigate the steady-state spontaneous emission of a V-type three-level atom, with the coherence between the two upper levels modified and controlled via incoherent pumping to a fourth auxiliary level. The external ...
Hall effect at a tunable metal-insulator transition
(American Physical Society, 2003)
Using a rotating magnetic field, the Hall effect in three-dimensional amorphous GdxSi1-x has been measured in the critical regime of the metal-insulator transition for a constant total magnetic field. The Hall coefficient ...
Differential sum rule for the relaxation rate in dirty superconductors

Fast noise in the Landau-Zener theory RID B-5617-2009
(American Physical Society, 2003)
We study the influence of a fast noise on Landau-Zener transitions. We demonstrate that a fast colored noise much weaker than the conventional white noise can produce transitions itself or can change substantially the ...
Ferromagnetic transition temperature enhancement in (Ga,Mn)As semiconductors by carbon codoping
(American Physical Society, 2003)
We present a theoretical study of (Ga,Mn)(As,C) diluted magnetic semiconductors with high C acceptor density that combines insights from phenomenological model and microscopic approaches. A tight-binding coherent-potential ...
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" ...
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 ...
Large mass dileptons from the passage of jets through a quark gluon plasma
