TLDR
In this paper, a quasiclassical approach to coherent spontaneous emission from a system of two-level atoms interacting with a quantized radiation field is presented. But the quantum effects that are lost in the selfconsistent field approximation are not considered.Abstract:
Coherent spontaneous emission from a system of $N$ two-level atoms interacting with a quantized radiation field is treated for the case in which Dicke's "cooperation number" $r$ is macroscopically large. It is shown how to modify the quasiclassical approach to this problem to incorporate quantum effects that are lost in the self-consistent-field approximation. The statistics of the emitted radiation are found to vary markedly with the initial state of the system of atoms. The photon statistics tend to that typical of blackbody radiation when the initial state of the atomic system is that which would result from incoherent pumping ($m\ensuremath{\sim}r$). When, on the other hand, the atoms are initially in a superradiant state ($m\ensuremath{\ll}r$), the emitted radiation may be represented approximately by a coherent state.read more

The Jaynes-Cummings Model

TL;DR: The Jaynes-Cummings model was used to examine the classical aspects of spontaneous emission and reveal the existence of Rabi oscillations in atomic excitation probabilities for fields with sharply defined energy as mentioned in this paper.

Coherence in Spontaneous Radiation Processes
TL;DR: In this article, the authors considered a radiating gas as a single quantum-mechanical system, and the energy levels corresponding to certain correlations between individual molecules were described, where spontaneous emission of radiation in a transition between two such levels leads to the emission of coherent radiation.

Comparison of quantum and semiclassical radiation theories with application to the beam maser
E.T. Jaynes,F.W. Cummings +1 more
TL;DR: In this article, it was shown that the semiclassical theory, when extended to take into account both the effect of the field on the molecules and the effects of the molecules on the field, reproduces the same laws of energy exchange and coherence properties as the quantized field theory, even in the limit of one or a few quanta in the field mode.

The Quantum Theory of Optical Coherence
TL;DR: In this paper, a succession of correlation functions for the complex field strengths is defined, and a fully coherent field is defined as one whose correlation functions satisfy an infinite succession of stated conditions.

B. R. Mollow,Roy J. Glauber +1 more
TL;DR: In this article, the amplification of electromagnetic fields is analyzed in a quantum-mechanical context by discussing the behavior of a simple theoretical model of the parametric amplifier, which is described by means of the time-dependent density operator for the system.
