论文摘要
我们研究了从定期调制的量子光系统中的光子散射。对于节能量子光学系统的激发单，我们将系统的频域N-光子散射矩阵的分析结构与其有效的哈密顿量的Floquet分解联系起来。此外，结果表明，相对于调制频率的一阶贡献对传输或相等的n-photon相关光谱在本质上是完全几何的，即仅取决于汉密尔顿轨迹，而不取决于所应用的调制的确切性质。
We study the scattering of photons from periodically modulated quantum-optical systems. For excitation-number conserving quantum optical systems, we connect the analytic structure of the frequency-domain N-photon scattering matrix of the system to the Floquet decomposition of its effective Hamiltonian. Furthermore, it is shown that the first order contribution to the transmission or equal-time N-photon correlation spectrum with respect to the modulation frequency is completely geometric in nature i.e. it only depends on the Hamiltonian trajectory and not on the precise nature of the modulation being applied.
