Spontaneous emission modification via quantum interference with energy shifts remained

ORAL

Abstract

Quantum interference in spontaneous emission from a four-level atom is investigated with the counter rotating terms and the energy shifts included. The atom has two upper levels coupled to a common lower level by the same vacuum modes and is driven by a coherent field to an auxiliary level. The effect of the counter rotating terms in coupling through the vacuum modes is taken into account by a unitary transformation method. We show how the quantum interference due to the energy shifts effects the spontaneous emission spectrum.
