Quenching the collective effects on the two-photon correlation from two double-raman atoms

We obtain an analytical expression for two-photon correlation G((2)) from two atoms driven in a double-Raman (or Lambda) configuration where collective effects such as superradiant, subradiant, and dipole-dipole interaction are included. It is found that the collective effects on the G((2)) can be q...
