Paper Abstract

Spontaneous emission in atomic system arises due to the interaction of atoms with environmental modes. Atomic coherence and quantum interference are the most important mechanisms for controlling the spontaneous emission. We show that under certain conditions complete quenching of spontaneous emission is possible. By using V type three level system driven by two fields, the phase dependence of quantum interference is investigated. The Fano type and P type interference mechanism in atomic coherence system driven by microwaves are investigated. In particular we find that both phase dependence interference mechanism may be destructive simultaneously and thus lead to spontaneous emission cancellation in different parts of the spectrum. One of the most important applications of this system is the refractive index enhancement.
