摘要

在这项工作中，我们重点研究量子相关性，特别是塔维斯-康明斯模型中的纠缠、量子转向和贝尔非局域性。这项研究结合空腔中存在的各种场来研究这些量子相关性。研究结果揭示了在热态、相干态和挤压真空态的影响下，两个两级原子中量子关联的层次结构--纠缠、量子转向和贝尔非局域性。动态过程显示出一定的振荡，特别强调非对称量子转向的存在。

Entanglement, quantum steering, and Bell nonlocality in the Tavis–Cummings system

In this work, we focus on quantum correlations, specifically entanglement, quantum steering, and Bell nonlocality within the Tavis–Cummings model. This study investigates these quantum correlations in the context of various fields existing in the cavity. The findings reveal the hierarchy of quantum correlations—entanglement, quantum steering, and Bell nonlocality—in two two-level atoms under the influence of thermal, coherent, and squeezed vacuum states. The dynamic process demonstrates certain oscillations, with particular emphasis on the presence of asymmetric quantum steering.
