具有双模运算符和相位运算符的广义Jaynes-Cummings模型中的几何相位

Geometric Phase in a Generalized Jaynes-Cummings Model with Double Mode Operators and Phase Operators

通过使用Lewis-Riesenfeld不变理论,已经研究了具有双模运算符和相位运算符的广义Jaynes-Cummings模型中的几何相位。与动力学相位相比,一个周期情况下的几何相位与双光子场的频率无关,光子和原子之间的耦合系数以及原子跃迁频率。显然,几何相具有纯几何和拓扑特征,这意味着几何相位代表了厄米线性束中的和乐。

By using the Lewis-Riesenfeld invariant theory, the geometric phase in a generalized Jaynes-Cummings model with double mode operators and phase operators has been studied. Compared with the dynamical phase, the geometric phase in a cycle case is independent of the frequency of the double photon field, the coupling coefficient between photons and atoms, and the atom transition frequency. It is apparent that the geometric phase has the pure geometric and topological characteristics, which means that the geometric phase represents the holonomy in the Hermitian linear bundles.
