The influence of quantum interference on spontaneous emission

В. И. Савченко, A. A. Panteleev, А. Н. Старостин

Abstract

Spontaneous relaxation of a three-level degenerate scheme is investigated. Two upper levels are coupled by the same quantum mode to the lower level. It is shown that the quantum interference does not modify spontaneous relaxation in free space unless the angular momenta of the upper levels are equal. However in a cavity interference can lead to modified spontaneous emission for any combination of the upper levels. Interaction of the atom with the laser field may lead to complete suppression of spontaneous emission if the lower level is the ground state.
