A model of radiation by multi-atoms is discussed. System A, composed of N atoms with two energy levels, is coupled with a single-mode radiation B. A and B are in turn coupled with two thermal reservoirs D and C respectively, and we also assume that all atoms which are located within a wave length of the radiation field have the same phase. Then under the approximation of long wave, rotating wave and mean fields, by introducing Markov approximation after using the method of density matrix, we have derived the...

A model of radiation by multi-atoms is discussed. System A, composed of N atoms with two energy levels, is coupled with a single-mode radiation B. A and B are in turn coupled with two thermal reservoirs D and C respectively, and we also assume that all atoms which are located within a wave length of the radiation field have the same phase. Then under the approximation of long wave, rotating wave and mean fields, by introducing Markov approximation after using the method of density matrix, we have derived the of equations motion for systems A and B respectively. These equations are concerning with the following processes: the spontaneous emission of single atom, the absorption and induced emission stimulated by thermal radiation, the induced emission of N atoms stimulated by single mode coherent state radiation as well as the coherent spontaneous emission of this multi-atoms system. The latter two processes are actually the two kinds of superradiance originated from Dicke model and had been investigated previonsly. We have analysed these five processes by numerical calculations. Besides, the influence of these processes upon the evolution of atomic system attaining thermal equilibrium and the increase of entropy is also discussed. It is pointed out that the correlations inside a multi-atoms system would not be destroyed by coherent spontaneous emission, in contrast with the incoherent one which leads to the change of entropy in atomic system. However, only when the entropy of the two reservoirs has been taken into account, will it be possible to demonstrate the mono-tonic increase in total entropy.

本文讨论一个多原子辐射模型:N个有两能级的原子体系(A),与一个单模辐射(B)彼此耦合,A和B又分别同热库D和C耦合,假设在辐射场波长范围内所有原子有相同的相位,则在长波、旋转波和平均场近似下,用密度矩阵方法,引入Markov近似,便可导得A,B两体系的运动方程,这一组方程包含了单原子的自发辐射和热辐射引起的吸收、感应辐射,同时也包含了单模相干态辐射引起的N个原子的感应辐射以及这多原子体系的相干自发辐射过程。后两种过程实际上是始于Dicke模型而后曾被人们多次讨论过的两类超辐射过程,我们对上述五种过程进行了讨论和数值计算。此外又讨论了这些过程对原子体系趋向热平衡和熵增加的影响,指出原子相干自发辐射不会破坏多原子体系的关联,而非相干自发辐射才会引起原子体系熵的变化,然而只有将热库的熵也算在一起时,才显示出总的熵单调增加。

Using the Jaynes-Cummings model of a single two-level atom interacting with a single radiation-field mode, we find the compound grand partition function (CGPF) in thermodynamical equiliblium for the atom-radiation system. In terms of partial derivatives of the CGPF with respect to the chemical potential of photons, we obtain the averages the variance and the second order correlation function of the photon number distribution. We show that th einteraction produces the effect on the photon number distribution...

Using the Jaynes-Cummings model of a single two-level atom interacting with a single radiation-field mode, we find the compound grand partition function (CGPF) in thermodynamical equiliblium for the atom-radiation system. In terms of partial derivatives of the CGPF with respect to the chemical potential of photons, we obtain the averages the variance and the second order correlation function of the photon number distribution. We show that th einteraction produces the effect on the photon number distribution in the thermal equilibrium in a form of perturbation.

We derive a set of equations characterizing the quantum statistical properties of Jaynes-Cummings model, which may be used to describe overall the dynamical and statistical aspects in the interaction between a two-level atom and a single mode of the radiation field. Both interactions of a two-level atom with a vacuum field and a excited atom with a coherent field, as examples, are discussed in detail. Finally, the practicality of the above-mentionedi theoretical studies is demonstrated.
