Light can mediate strong interactions between cold and dense atomic ensembles, such that the atoms respond to light cooperatively. Some of the recent findings in experimental laboratories and numerical simulations for these systems have been incompatible with the textbook wisdom of standard optics in a dielectric medium. In this programme we want to explain some of these failings and also to develop a novel platform for utilizing these strong interactions in the manipulation of light. Individual quantum particles have now been accurately controlled in experiments already for quite some time. However, technologically important many-particle systems have so far been beyond such control. The goal of the programme is to improve the control and manipulation of atomic ensembles and to guide experimentalists to develop better next generation optical devices and technologies based on quantum physics.

光可以介导冷原子和致密原子之间的强相互作用，使原子对光协同响应。最近在实验实验室和这些系统的数值模拟中的一些发现与教科书中关于介电介质中标准光学的智慧不相容。在这个节目中，我们想要解释其中的一些缺陷，并开发一个新的平台，利用这些强相互作用来操纵光。单个量子粒子在实验中被精确控制已经有一段时间了。然而，技术上重要的多粒子系统到目前为止还无法控制。该计划的目标是改善对原子系综的控制和操纵，并指导实验学家基于量子物理学开发更好的下一代光学器件和技术。
