Abstract

In this paper, we show theoretically that the fields scattered by a bichromatically driven V-type three-level atom exhibit large and asymmetric amplitude–intensity correlations. These features result from the different fluctuations of the amplitude and intensity field operators and the competition among transitions. The amplitude–intensity correlations of resonance fluorescence, with its large third-order fluctuations, describe phase-dependent nonclassical features of the emitted field in addition to the second-order measure related to squeezing. We also calculate spectra and variances of these correlations and intensity–intensity correlations, which provide a wealth of supporting information.
