摘要

早期量子光学的Jaynes-Cummings模型是从与离散空间晶格的单个边缘相关的基本量子赫兹偶极子激发的电磁场的离散空间离散时间公式(FDTD公式)的角度来检验的。量子赫兹偶极子是一个自然的2能级原子系统，电磁场在偶极子周围的离散空间中的量子动力学，用场空间上的泛函积分来描述，本质上是一种通过寻找场作用拉格朗日泛函S为平稳的场分布来求解FDTD方程的随机(蒙特卡罗)算法。

Quantum optics and the discrete-space discrete-time Jaynes-Cummings model

The Jaynes-Cummings model of early quantum optics is examined from the point of view of a discrete-space discrete-time formulation of the electromagnetic field (the FDTD formulation) excited by an elementary quantum Hertzian dipole associated to a single edge of the discrete-space lattice. The quantum Hertz dipole is a natural 2-level atomic system, and the quantum dynamics of the electromagnetic field in the discrete space surrounding the dipole, described by functional integrals over field space, is essentially a stochastic (Monte-Carlo) algorithm for solving the FDTD equations by searching for the field distribution about which the field action Lagrangian functional S is stationary.
