论文摘要
在强耦合方案中控制基于光晶的量子系统，可以在当今体系结构中探索多体物理的量子模拟。例如，腔QED网络中的原子场相互作用为量子信息处理提供了控制和可扩展性。在这里，我们提出了在非平衡场景中对单体和两体Jaynes-Cummings系统的控制，这使我们能够建立北极分支的相干和不相互交换的条件。我们的发现提供了一种系统的方法来操纵Polaritons的互换，我们适用于揭示Mott绝缘子和类似超流体状态之间过渡的新见解。此外，我们通过触发腔和原子损失来研究吸收光谱中的不对称性，这是原子腔腔内失调和光子跳跃的函数的函数。
Controlling light-matter based quantum systems in the strong coupling regime allows for exploring quantum simulation of many-body physics in nowadays architectures. For instance, the atom-field interaction in a cavity QED network provides control and scalability for quantum information processing. Here, we propose the control of single- and two-body Jaynes-Cummings systems in a non-equilibrium scenario, which allows us to establish conditions for the coherent and incoherent interchange of polariton branches. Our findings provide a systematic approach to manipulate polaritons interchange, that we apply to reveal new insights in the transition between Mott Insulator- and Superfluid-like states. Furthermore, we study the asymmetry in the absorption spectrum by triggering the cavity and atomic losses as a function of the atom-cavity detuning and photon's hopping.
