Resumen

This thesis is devoted to the investigation of polaritons supported by organic microcavities. Two distinct types of such states are present in these systems, namely, exciton-polaritons and vibro-polaritons, formed upon hybridization of molecular excitations with optical and mid-infrared photons respectively. We provide fundamental explorations of both scenarios, by employing models of increased complexity that are tractable in the framework of quantum optics and quasi-exact methods in condensed matter physics. Our results demonstrate the crucial role of the molecular environment and phonons in determining the steady-state linear spectra, the internal structure and the short-time dynamics of organic polaritons.
