TLDR
In this paper, the collective interaction of N identical two-level atoms with a quantum electromagnetic field in a perfect cavity is considered, and it is shown that the initial atomic state coherence introduces some coherent features in the dynamics of the initially thermal field.About:

Dicke model: quantum nonlinear dynamics and collective phenomena
S. M. Chumakov,M. Kozierowski +1 more
TL;DR: In this paper, the resonant interaction of A initially unexcited two-level atoms with single-mode Fock, coherent and thermal cavity fields of arbitrary intensity was studied, and two mechanisms lead to a spread of the eigenfrequencies: one is due to the photon-number distribution in the initial state and the other reflects the cooperativity of the system.

Comparison of the Dicke model and the Hamiltonian for n quantum dots
TL;DR: In this article, the authors compare the Dicke and Jaynes Cummings dynamics of atoms described by the Hamiltonian of Quantum Dots, and develop the SU(2) perturbative approach in the regimen where the excitation number (atoms + photons) is larger than the number of atoms L.

The Cummings-Tavis model as a nonlinear quantum amplifier
TL;DR: In this paper, a system of N identical two-level atoms interacting with the single mode of the boson field is considered in the rotating-wave approximation, and the uncertainty of the field is interpreted in terms of the noise of the amplifier.

A 2dvEv- bit distributed algorithm for the directed Euler trail problem
Wen-Huei Chen,Chuan Yi Tang +1 more
TL;DR: The algorithm can be used as a building block for solving other distributed graph problems, and can be slightly modified to run on a strongly-connected diagraph for generating the existent Euler trail or to report that no Euler trails exist.

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.

Observation of quantum collapse and revival in a one-atom maser.
TL;DR: The dynamics of the interaction of a single Rydberg atom with a single mode of an electromagnetic field in a superconducting cavity was investigated and the quantum collapse and revival predicted by the Jaynes-Cummings model were demonstrated experimentally for the first time.

Atomic coherent states in quantum optics
TL;DR: In this paper, a suitable model Hamiltonian for the description of the interaction between N atoms and an electromagnetic field confined in a cavity of finite volume is proposed, where the Bose operators describe the k-th field mode and S i ±,S 3i are Pauli operators describing the atom located at position x i as a two-level system.

Atomic Coherent States in Quantum Optics
TL;DR: In this paper, it was shown that the atomic coherent states are the quantum analogs of classical dipoles, and that they can be produced by classical fields, and the derivation of the properties of the quantum coherent states is made easier by the use of a powerful disentangling theorem for exponential angular momentum operators.
