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. 000153084 536__ $$9info:eu-repo/grantAgreement/ES/DGA/Q-MAD$$9info:eu-repo/grantAgreement/ES/MCIU/MAT2017-88358-C3-1-R 000153084 540__ $$9info:eu-repo/semantics/openAccess$$aby$$uhttps://creativecommons.org/licenses/by/4.0/deed.es 000153084 590__ $$a8.449$$b2020 000153084 591__ $$aMATERIALS SCIENCE, MULTIDISCIPLINARY$$b49 / 333 = 0.147$$c2020$$dQ1$$eT1 000153084 591__ $$aNANOSCIENCE & NANOTECHNOLOGY$$b25 / 106 = 0.236$$c2020$$dQ1$$eT1 000153084 591__ $$aPHYSICS, APPLIED$$b20 / 160 = 0.125$$c2020$$dQ1$$eT1 000153084 591__ $$aOPTICS$$b9 / 99 = 0.091$$c2020$$dQ1$$eT1 000153084 592__ $$a2.717$$b2020 000153084 593__ $$aAtomic and Molecular Physics, and Optics$$c2020$$dQ1 000153084 593__ $$aElectronic, Optical and Magnetic Materials$$c2020$$dQ1 000153084 593__ $$aElectrical and Electronic Engineering$$c2020$$dQ1 000153084 593__ $$aBiotechnology$$c2020$$dQ1 000153084 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000153084 700__ $$0(orcid)0000-0003-4478-1948$$aZueco, David$$uUniversidad de Zaragoza 000153084 700__ $$0(orcid)0000-0001-9273-8165$$aMartin-Moreno, Luis$$uUniversidad de Zaragoza 000153084 7102_ $$12003$$2395$$aUniversidad de Zaragoza$$bDpto.
