摘要：

本文给出了超冷玻色和费米气体与真空电磁场和激光光子相互作用的严格微观量子理论。主要的注意力已经支付给动力学偶极-偶极相互作用的一致考虑。所发展的理论与介质中电磁场正则量子化的一般原理是一致的。本文从QED第一性原理出发，导出了原子产生和湮灭算符的Maxwell-Bloch方程组和激光场的传播方程，可用于原子光学中各种线性和非线性现象的自洽分析。所有已知的用于描述辐射场中超冷原子系综行为的方程都可以从我们的低密度极限下的一般方程组得到。

英文摘要：

We present the rigorous microscopic quantum theory of the interaction of ultracold Bose and Fermi gases with the electromagnetic field of vacuum and laser photons. The main attention has been paid to the consistent consideration of dynamical dipole-dipole interactions. The theory developed is shown to be consistent with the general principles of the canonical quantization of electromagnetic field in a medium. Starting from the first principles of QED we have derived the general system of Maxwell-Bloch equations for atomic creation and annihilation operators and the propagation equation for the laser field which can be used for the self-consistent analysis of various linear and nonlinear phenomena in atom optics at high densities of the atomic system. All known equations which are used for the description of the behaviour of an ultracold atomic ensemble in a radiation field can be obtained from our general system of equations in a low-density limit.
