Entanglement generation in a two-mode quantum beat laser RID A-4660-2010
(American Physical Society, 2007)
We analyze the quantum correlations between side modes of a quantum beat laser when a two-level atomic medium is driven strongly by a classical field. The squeezing and the entanglement generation of the cavity radiation ...
Spectral narrowing via quantum coherence
(American Physical Society, 2006)
We have studied the transmission through an optically thick Rb-87 vapor that is illuminated by monochromatic and noise-broadened laser fields in Lambda configuration. The spectral width of the beat signal between the two ...
Proposal for direct measurement of concurrence via visibility in a cavity QED system
(American Physical Society, 2008)
An experimental scheme is proposed that allows direct measurement of the concurrence of a two-qubit cavity system. It is based on the cavity-QED technology using atoms as flying qubits and relies on the identity of the ...
Bilingual language lateralization: A meta-analytic tale of two hemispheres
(Elsevier, 2007-03)
Two meta-analyses of 66 behavioral studies examined variables influencing functional cerebral lateralization of each language of brain-intact bilingual adults. Functional lateralization was found to be primarily influenced ...
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 ...
Subwavelength atom localization via amplitude and phase control of the absorption spectrum
(American Physical Society, 2005)
We propose a scheme for subwavelength localization of an atom conditioned upon the absorption of a weak probe field at a particular frequency. Manipulating atom-field interaction on a certain transition by applying drive ...
Quantum teleportation of an arbitrary superposition of atomic Dicke states
(American Physical Society, 2005)
We propose a scheme for teleporting an arbitrary superposition of entangled Dicke states of any number of atoms (qubits) between two distant cavities. Our method relies on adiabatic passage using multi-atom dark states in ...
Manipulation of the Raman process via incoherent pump, tunable intensity, and phase control
(American Physical Society, 2008)
We present a proposal to manipulate the Raman process via incoherent pump, tunable intensity, and phase control of the driving fields. It is found that Raman absorptive peaks can become Raman gain peaks by controlling the ...
Measurement of ground-state decoherence via interruption of coherent population trapping
(American Physical Society, 2007)
We examine the role of ground-state coherence on the fluorescence from the excited state in a three-level Lambda system under continuous-wave excitation. When resonantly pumped, the fluorescence is strongly affected by any ...
Enhancement of field generation via maximal atomic coherence prepared by fast adiabatic passage in Rb vapor
(American Physical Society, 2004)
We have experimentally demonstrated the enhancement of coherent Raman scattering in Rb atomic vapor by exciting maximal atomic coherence with fractional stimulated Raman adiabatic passage. Experimental results are in good ...
