The goal of this project is to theoretically characterize the many-body dynamics of a quantum degenerate gas of bosonic atoms, which mutually interact via two competing mechanisms: the forces due to the coupling to a Rydberg state (Rydberg dressing) and the optomechanical long-range forces due to multiple scattering of photons in a high-finesse cavity. Both forces induce ordering, their interplay is to large extent unexplored and its systematic characterization would contribute to shed light onto the quantum physical processes undelying complex structure formation. Our analysis will refer at all stages to existing experimental realizations. The main expected result is the full characterization of the atoms and cavity stationary state as a function of the relative strength of the two competing interactions and the corresponding signatures imprinted in the cavity-emitted light.

该项目的目标是从理论上表征玻色子原子的量子简并气体的多体动力学，这些气体通过两种竞争机制相互作用：由于与里德伯态（里德伯敷料）耦合而产生的力，以及由于高精细腔体中光子的多次散射而产生的光机械长程力。这两种力都会产生有序性，它们的相互作用在很大程度上尚未被探索，其系统表征将有助于揭示复杂结构形成背后的量子物理过程。我们的分析将在所有阶段参考现有的实验实现。主要预期结果是原子和腔稳态的完整表征，作为两种竞争相互作用的相对强度的函数以及腔发射光中印记的相应特征。
