Electromagnetically induced transparency (EIT) involving highlyexcited Rydberg states has become a powerful technique to mediatestrong synthetic interactions between single photons in an atomicmedium. Based upon our experimental and theoretical findings on thenature of the nonlinear, non-local susceptibility under Rydberg-EITconditions during the first funding period of the SPP GiRyd, wepropose to extend our investigations to stationary ground-statepolaritons which acquire interactions through a novel Rydbergdressingscheme. This approach will allow us to study the photondynamics in the two-dimensional geometry transverse to the lightpropagation, and thereby open the door to many-body phenomena byaccommodating unprecedentedly larger number of interactingphotons. Moreover, the use of stationary-light polaritons composed ofground-state excitations yields drastically improved coherenceproperties and enhanced interaction times, while the proposedRydberg-dressing scheme will provide a new level of interactioncontrol in Rydberg-EIT settings and make it possible to realizerepulsive photons for the first time in experiments. The proposedproject thus provides unique opportunities for the exploration of nonequilibriummany-body quantum dynamics and the emergence ofexotic quantum states of light, both in theory and experiment.

电磁感应透明（EIT）是一种利用高激发里德堡态实现单光子强合成相互作用的有效方法。基于我们在SPP GiRyd第一个资助期内对Rydberg-EIT条件下非线性、非局域极化率性质的实验和理论发现，我们提出将我们的研究扩展到通过一种新的Rydbergdressing方案获得相互作用的稳态基态极化激元。这种方法将使我们能够在二维几何中研究光传播的横向光子动力学，从而通过容纳前所未有的大量相互作用光子来打开多体现象的大门。此外，使用由基态激发组成的定常光极化激元产生了显著改善的相干特性和增强的相互作用时间，而所提出的Rydberg-dressing方案将在Rydberg-EIT设置中提供新水平的相互作用控制，并使在实验中首次实现脉冲光子成为可能。因此，该项目为非平衡多体量子动力学的探索和光的奇异量子态的出现提供了独特的机会，无论是在理论上还是在实验上。
