Photon-antibunching and sub-Poissonian photon statistics
Xiang Zou, L. Mandeļ · Physical Review A · 1990
It is shown by example that sub-Poissonian photon-counting statistics need not imply photon antibunching, but can be accompanied by photon bunching, i.e., by the tendency of two photons to be close together more frequently than further apart. Some comments on the relation between antibunching and sub-Poissonian statistics are made.
