Hausinger, Johannes and Grifoni, Milena (2010) Qubit-oscillator system: An analytical treatment of the ultrastrong coupling regime. Phys. Rev. A 82 (6), 062320.
We examine a two-level system coupled to a quantum oscillator, typically representing experiments in cavity and circuit quantum electrodynamics. We show how such a system can be treated analytically in the ultrastrong coupling limit, where the ratio g/Ω between coupling strength and oscillator frequency approaches unity and goes beyond. In this regime the Jaynes-Cummings model is known to fail ...
