Photon-photon correlations as a probe of vacuum-induced coherence effects
(American Physical Society, 2008-03-27)
We show how the effects of vacuum-induced coherence can be realized by studying photon-photon correlation in the pi-polarized fluorescence in the j=1/2 to j=1/2 transition. These effects should thus be observable in ...
Transport and quantum walk of nonclassical light in coupled waveguides
(American Physical Society, 2008-10-08)
We study the transport and quantum walk of nonclassical light in an array of coupled waveguides which have properties like very low decoherence and thus making them ideal for storage of quantum information. We show how ...
Entanglement of two distant Bose-Einstein condensates by detection of Bragg-scattered photons
(American Physical Society, 2008-07-31)
We show that it is possible to generate entanglement between two distant Bose-Einstein condensates by detection of Hanbury-Brown-Twiss-type correlations in photons Bragg scattered by the condensates. Upon coincident detection ...
Quantum optical spring
(American Physical Society, 2008-07-22)
We study the dynamics of the quantum optical spring, i.e., a spring whose spring constant undergoes discrete jumps depending on the quantum state of another system. We show the existence of revivals and fractional revivals ...
Quantum interferences in cooperative Dicke emission from spatial variation of the laser phase
(American Physical Society, 2008-10-06)
We report generation of a new quantum interference effect in spontaneous emission from a resonantly driven system of two identical two-level atoms due to the spatial variation of the laser phase at the positions of the ...
Nonclassical correlation of polarization-entangled photons in a biexciton-exciton cascade
(IOP Publishing, 2008-11-07)
We develop a theoretical model to study the intensity–intensity correlation of polarization-entangled photons emitted in a biexciton–exciton cascade. We calculate the degree of correlation and show how polarization ...
Electromagnetic field induced modification of branching ratios for emission in structured vacuum
(IOP Publishing, 2008-01-17)
We report a fundamental effect of the electromagnetic field induced modification of the branching ratios for emission into several final states. The modifications are especially significant if the vacuum into which the ...
