Strongly correlated few-body states of Rydberg polaritons (A08)

通过开放系统控制来创建和稳定许多有趣的身体状态是基于定制的水库和强相互作用之间的相互作用。在这个项目中，我们通过控制耦合到超冷镱气体中的里德伯态来实现单个光子之间的有效相互作用。利用第一次原子物种与两个价电子的里德伯介导的光子相互作用，我们的目标是实现强相关系统的几个到许多光子的高度控制的相干相互作用以及耗散通道。最初集中在一个自下而上的方法来构建多达10个光子的一维系统，我们的目标是研究多光子相关的出射光，并探讨有效量子场论相互作用里德伯极化激元的适用性。

The creation and stabilization of interesting many body states via open system control is based on the interplay between tailored reservoirs and strong interactions. In this project, we implement effective interaction between individual photons via controlled coupling to Rydberg states in an ultracold ytterbium gas. Utilizing for the first time an atomic species with two valence electrons for Rydberg-mediated photon interaction, we aim to realize strongly correlated systems of few to many photons with high degrees of control over both the coherent interaction as well as the dissipation channels. Focussing initially on a bottom-up approach to construct one-dimensional systems of up to ten photons, we aim to study multi-photon correlations in the outgoing light and explore the applicability of effective quantum field theories to interacting Rydberg polaritons.
