The CR terms do not have a strong effect on the spectrum even for moderately large values of the exciton-photon interaction. However, it is shown that the polariton subspace is governed by an effective Quantum-Rabi Hamiltonian, where polaritons act as a two-level system and the phonons play the role of cavity photons. The effect of the CR terms is amplified in the dynamics: as the vibrations reduce the effective photon-exciton coupling, small Bloch-Siegert energy shifts can bring the system out of resonance. info:eu-repo/grantAgreement/ES/DGA/Q-MAD info:eu-repo/grantAgreement/ES/MCIU/MAT2017-88358-C3-1-R info:eu-repo/semantics/openAccess by https://creativecommons.org/licenses/by/4.0/deed.es 8.449 2020 MATERIALS SCIENCE, MULTIDISCIPLINARY 49 / 333 = 0.147 2020 Q1 T1 NANOSCIENCE & NANOTECHNOLOGY 25 / 106 = 0.236 2020 Q1 T1 PHYSICS, APPLIED 20 / 160 = 0.125 2020 Q1 T1 OPTICS 9 / 99 = 0.091 2020 Q1 T1 2.717 2020 Atomic and Molecular Physics, and Optics 2020 Q1 Electronic, Optical and Magnetic Materials 2020 Q1 Electrical and Electronic Engineering 2020 Q1 Biotechnology 2020 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Zueco, David Universidad de Zaragoza (orcid)0000-0003-4478-1948 Martin-Moreno, Luis Universidad de Zaragoza (orcid)0000-0001-9273-8165 2003 395 Universidad de Zaragoza Dpto.
