In this project we will address the behaviour of many-body systems embedded in (optical and microwave) cavities. Investigations will focus in particular on strongly correlated and quantum ordered 2D systems. The presence of a cavity enables reaching the ultra-strong limit of light-matter interaction, which can in turn lead to the emergence of novel quantum phases of matter. The field has recently emerged as a hot topic, with more and more papers (in particular experimental ones) being published on the control of quantum phases realised in van der Waals materials. Intriguingly, the form acquired by such phases can depend on the gauge chosen for the electromagnetic radiation. This fact has been recently studied for model systems such as ensembles of dipoles or continuous (jellium) models. However, no attempt has been made at investigating this physics in realistic models of materials, which will be the focus of this project.

在这个项目中，我们将解决嵌入（光学和微波炉）腔中的多体系统的行为。调查将特别关注密切相关和量子有序的2D系统。腔的存在使得光 - 肌电相互作用的超高极限，进而导致物质的新量子阶段的出现。该领域最近成为一个热门话题，越来越多的论文（特别是实验性的论文）在控制范德华材料中实现的量子阶段的控制方面发表。有趣的是，此类阶段获得的形式可以取决于为电磁辐射选择的量规。最近已经研究了该事实的模型系统，例如偶极子或连续模型的组合。但是，尚未尝试在现实的材料模型中研究这种物理学，这将是该项目的重点。
