On the bichromatic excitation of a two-level atom with squeezed light

Analytical results for the dynamical evolution of a single two-level atom coupled to an ordinary heat bath and bichromatically excited with two finite bandwidth squeezed fields are presented by solving the Heisenberg equations of motion. Photon statistics of the system in terms of the second-order intensity-intensity correlation function are also discussed. Transient fluorescent intensity as well as intensity correlation function exhibit oscillatory phenomenon even in the weak field limit. The latter also shows enhanced delayed bunching effect. All these effects are sensitive to the bandwidth of squeezed light.
