Universidad de Zaragoza Ultrastrongly dissipative quantum Rabi model 2019 Access copy available to the general public Unrestricted We discuss both the spectrum and the dynamics of cavity QED in the presence of dissipation beyond the standard perturbative treatment of losses. Using the dynamical polaron ansatz and matrix-product state simulations, we discuss the case where both light-matter g coupling and system-bath interaction are in the ultra-strong-coupling regime. We provide a critical g for the onset of Rabi oscillations. Besides, we demonstrate that the qubit is dressed by the cavity and dissipation. Such a dressing governs the dynamics and, thus, it can be measured. Finally, we sketch an implementation for our theoretical ideas within circuit QED technology. info:eu-repo/grantAgreement/ES/DGA/CAM PRICYT/QUITEMAD+S2013-CE-2801 info:eu-repo/grantAgreement/ES/DGA/Q-MAD info:eu-repo/grantAgreement/ES/MINECO/FIS2015-70856-P info:eu-repo/grantAgreement/ES/MINECO/MAT2017-88358-C3-1-R info:eu-repo/grantAgreement/EUR/QUANTERA/SUMO info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 2.777 2019 PHYSICS, ATOMIC, MOLECULAR & CHEMICAL 12 / 36 = 0.333 2019 Q2 T2 OPTICS 31 / 97 = 0.32 2019 Q2 T1 1.416 2019 Atomic and Molecular Physics, and Optics 2019 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion García-Ripoll, J. 2003 395 Universidad de Zaragoza Dpto.
