Research paperTheoreticalOrganic–Inorganic Polaritonics: Linking Frenkel and Wannier–Mott ExcitonsV. G. M. Duarte, A. J. Chaves, N. M. R. PeresarXiv preprint·2025·10.1002/cphc.201200734·arXiv:2504.09631AbstractWe develop a microscopic model for a hybrid organic–inorganic optical microcavity in which a 2D semiconductor and an organic molecular aggregate couple indirectly through cavity photons. Using a 3×3 Hamiltonian for photons, Wannier–Mott excitons, and Frenkel excitons, we predict hybrid exciton-polariton states with tunable double Rabi splitting and an enhanced splitting relative to a purely organic cavity. The model is illustrated using a tungsten sulfide monolayer and a cyanine dye, showing that detuning can merge the polariton branches into a single hybrid state and enabling tunable strong and ultrastrong coupling behavior.Read more
