Quantum-Electrodynamic Treatment of Spontaneous Emission in the Presence of an Applied Field
Carlos R. Stroud · Physical Review A · 1971
Spontaneous emission by a "two-level atom" interacting with a highly excited field mode is described using quantum electrodynamics without time-dependent perturbation theory. It is found that both the line shape and the Lamb shift are affected by the "applied field." Detailed solutions are presented as a function of the population of the "applied-field mode" and as a function of the detuning.
