标题： Cavity QED systems for steady-state sources of Wigner-negative light

摘要： 我们对由驱动的开放 Jaynes-Cummings 模型及其一些变体描述的光学腔 QED 系统进行了理论研究，作为稳态 Wigner 负光的潜在来源。 我们考虑腔连续输出场中的时间模式，并展示了在实验相关参数范围内其 Wigner 分布的显著负性。 我们考虑了单个和集体原子自旋系统的模型，并发现当自旋大小变化时，Wigner 分布负性具有丰富的结构。 我们还展示了一种有效的实现方式，仅使用一个 87Rb 原子，并基于单个基态超精细态中磁子能级之间的拉曼跃迁的激光和激光加腔驱动组合，实现了所有考虑的模型。 显示英文摘要

摘要： We present a theoretical investigation of optical cavity QED systems, as described by the driven, open Jaynes-Cummings model and some of its variants, as potential sources of steady-state Wigner-negative light. We consider temporal modes in the continuous output field from the cavity and demonstrate pronounced negativity in their Wigner distributions for experimentally-relevant parameter regimes. We consider models of both single and collective atomic spin systems, and find a rich structure of Wigner-distribution negativity as the spin size is varied. We also demonstrate an effective realization of all of the models considered using just a single 87Rb atom and based upon combinations of laser- and laser-plus-cavity-driven Raman transitions between magnetic sublevels in a single ground hyperfine state.
