    Abstract

    We investigate the Rabi Hamiltonian (or the Jaynes-Cummings model without the rotating-wave approximation), describing the coupling of a single mode of electromagnetic radiation to a two-level system, by means of the coupled cluster method. We find strong evidence for a second-order quantum phase transition.
