Single-atom cavity-enhanced absorption. I. Photon statistics in the bad-cavity limit
Perry R. Rice, H. J. Carmichael · IEEE Journal of Quantum Electronics · 1988
The photon statistics of the transmitted light from a driven cavity containing a single resonant two-level atom are studied in the bad-cavity limit. For weak driving fields, the second-order intensity correlation function shows novel nonclassical behavior due to the interference of the driving field and forward reradiation from the atom. This behavior is related to squeezing in the cavity transmission. A physical interpretation is given in terms of the reduced quantum state of the coupled atom-field system following photodetection.>
