COMPASS · Cavity cOntrol of quantuM PhAseS in nanophotonic cavitieS

The COMPASS project, acronym for ""Cavity cOntrol of quantuM PhAseS in nanophotonic cavitieS,"" delves into the theoretical exploration of inducing and controlling superconductivity and other many-body phases using nanophotonic cavities. Situated in the field of cavity quantum-electrodynamics (cQED), COMPASS leverages the strong-coupling light-matter interactions characteristic of hyperbolic phonon polariton (HPP) nanophotonic cavities. Offering a significant advancement over traditional Fabry-Pérot cavities, HPP cavities promise unprecedented control over electronic structures, potentially deepening our understanding of exotic superconductivity and introducing novel quantum states of matter. This project necessitates the development of novel theories for strongly correlated materials embedded in nanophotonic cavities, by merging solid-state, quantum optics, and many-body physics. The action will be carried out by Dr. Gian Marcello Andolina at Collège de France under the supervision of Dr. Marco Schirò. The project integrates the Researcher's advanced expertise in quantum nanophotonics and solid state physics with the Host's mastery of many-body theory. The multidisciplinary environment of the Hosting Institution will be pivotal for the success of the Action for the growth of the Researcher.""
