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 ...
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 ...
