Extended photon correlation in a negative-temperature medium
We show how two-photon correlation of a two-level amplifier in the small signal regime depends on the atomic populations and the propagation length. We predict that inverted population associated with negative temperature gives a very long correlation time even in the presence of decoherence, a usef...
