a Schematic representation of the coupling of material and field states producing hybrid light-matter polariton states P+ and P−. We explore here whether the formation of phonon-polaritons can modify electron-phonon interactions. b Sketch of a perovskite thin film in an optically transparent Fabry–Pérot cavity, with a tunable cavity length of ~100’s of μm, so that its fundamental mode resonates at THz frequencies
