HIGHER-ORDER SUB-POISSONIAN STATISTICS IN INTERACTION OF TWO TWO-LEVEL ATOMS WITH A SINGLE MODE COHERENT RADIATION
Journal Title: Indian Journal of Scientific Research - Year 2015, Vol 6, Issue 1
Abstract
In the present paper we study higher-order sub-Poissonian photon statistics in interaction of a single mode radiation initially in the coherent state with an assembly of two excited two-level atoms using the Hamiltonian, , in the natural system of units. Here, , a is the annihilation operator for radiation, and are the collective Dicke operators, g is the coupling constant, is the energy of the photons and the energy difference between the two atomic levels. We solve it exactly and conclude that higher-order sub-Poissonian photon statistics can be obtained for an arbitrary order by choosing suitably the square root of mean photon number of the coherent radiation and coupling time gt. Variations of higher-order sub-Poissonian photon statistics with parameters and gt have also been discussed.
