标题： Local vs non-local dynamics in cavity-coupled Rydberg atom arrays

摘要： 局域性是一个横贯性的原理，它支配着多体系统的量子动力学。 然而，对于嵌入腔体的系统，这种基本概念受到非局域腔模式的存在阻碍，为新的可能动力学行为留下了空间。 在这里，我们研究了一维里德伯原子阵列在耦合到全局腔模式下的低能激发的实时动力学。 我们推导出一个有效的描述，即一个蒂维斯-卡明斯-伊辛模型，其相图具有有序和无序相。 腔模式的非局域性质极大地影响了出现的介子和弦动力学。 介子与腔光子相干地混合，导致复合介子极化子激发。 弦不同与局部相互作用理论，由于底层域壁之间的非局域腔介导相互作用，它们获得了有限的动能。 最后，我们通过提出一个新的具体的实验蓝图，用于腔量子电动力学里德伯原子阵列模拟器，其中可以实现本文中描述的物理现象。 显示英文摘要

摘要： Locality is a transversal principle that governs quantum dynamics of many-body systems. However, for cavity embedded systems, such fundamental notion is hindered by the presence of non-local cavity modes, leaving space for new possible dynamical behaviors. Here, we investigate the real-time dynamics of low-energy excitations in one dimensional Rydberg atom arrays coupled to a global cavity mode. We derive an effective description in terms of a Tavis-Cummings-Ising model, whose phase diagram features ordered and disordered phases. The non-local nature of the cavity mode drastically affects the emergent meson and string dynamics. Mesons hybridize coherently with the cavity photons, leading to composite meson-polaritons excitations. Strings, differently from local interacting theories, acquire a finite kinetic energy thanks to non-local cavity-mediated interactions between the underlying domain-walls. We then conclude by presenting a new concrete experimental blueprint for a cavity QED Rydberg atom array simulator where the physics outlined in this work can be realized.
