Photon statistics of resonance fluorescence in a squeezed vacuum

Abstract
We present some effects of a squeezed vacuum on the photon statistics of a coherently driven two-level atom. The intensity-intensity correlation function g(2)(τ), Mandel’s response function Q(T), and the photon-counting distribution P(0,T) show the manifestation of the inhibition of atomic phase decay in the presence of a squeezed vacuum.
