Spontaneous emission of a three-level atom in a system of N atoms

Abstract

Cooperative spontaneous emission from a system of N three-level atoms in lambda and ladder configurations of the levels immersed in a high-Q two-mode cavity, when only one atom is initially excited to its highest level, is solved exactly in a completely quantised treatment.

Exact solution for spontaneous emission in the presence of N atoms

F.W. Cummings, Ali Dorri

$N$ two-level "atoms" are considered in interaction with a single-mode resonant electromagnetic field. The exact solution is given nonrelativistically for all times for the case of spontaneous emission, when only one atom is initially excited. The solution is given for the general case of the $N$ atoms in inequivalent mode positions.

Spontaneous emission by a fully excited system of three identical atoms

Helen S. Freedhoff

The Lehmberg-Agarwal master equation is used to study cooperative spontaneous emission by a system of three identical two-level atoms. A choice of basis states is described which allows an exact solution to be obtained for any geometrical configuration, any sample size, and any initial conditions of the atomic system, fully including both near-field and super-radiance effects.

An exact solution for the collective spontaneous emission from an assembly of N identical two-level atoms, placed into a resonant damped cavity and excited to a symmetrical Dicke state with only one atom in the excited state, is derived.

Spontaneous emission by a system ofNtwo-level atoms in terms of the SU(2)-group representations

M. Kozierowski, A. A. Mamedov, S. M. Chumakov

We consider cooperative spontaneous emission by an assembly of N two-level atoms immersed in a high-Q single-mode cavity, when s (s\ensuremath{\ll}N) atoms are initially excited. The atoms are noninteracting with each other except via the action of the electromagnetic field. The eigenvalues of the system and the time development of the mean energy of the atomic subsystem are presented in the form of power series in the parameter \ensuremath{\epsilon}=(N-s/2+1/2${)}^{\mathrm{\ensuremath{-}}1}$ using the SU(2)-group-representation technique.
