标题： Meson-polariton and string dynamics via cavity coupling in Rydberg atom array

摘要： 我们研究了在集体腔模存在的情况下，一维里德伯原子阵列中的介子和弦的实时动力学。我们推导了一个有效描述，即一个Tavis-Cummings-Ising模型，其相图包含有序相和无序相。在有序态上的单个畴壁表现出与伊辛模型中发现的畴壁不同的行为，由于光与物质之间的$U(1)$不变耦合，表现出强烈的各向异性。腔模的非局域性质则显著影响介子和弦的动力学。介子与腔光子相干混合，导致复合的介子-极化子激发。与局部相互作用理论不同，弦由于腔模介导的底层畴壁之间的非局域相互作用而获得有限的动能并自由传播。我们最后考察了腔损耗的影响，提出了一种主动利用腔模的状态制备协议，并提出了一个具体的实验蓝图。 显示英文摘要

摘要： We investigate the real time meson and string dynamics of one dimensional Rydberg atom arrays in presence of a collective cavity mode. We derive an effective description in terms of a Tavis-Cummings-Ising model, whose phase diagram features ordered and disordered phases. Single domain walls on top of ordered states behave differently from those found in Ising models, featuring strong anisotropy because of the $U(1)$ invariant coupling between light and matter. The non-local nature of the cavity mode is instead affecting meson and string dynamics drastically. Meson hybridizes coherently with the cavity photons, leading to composite meson-polariton excitations. Strings, differently from local interacting theories, acquire a finite kinetic energy and propagate freely thanks to the non-local interaction between the underlying domain-walls mediated by the cavity mode. We conclude by examining the effect of cavity losses, proposing a state-preparation protocol which actively uses the cavity mode, and presenting a concrete experimental blueprint.
