Abstract
We study the scattering of individual photons by a two-level system ultrastrongly coupled to a waveguide. The scattering is elastic for a broad range of couplings and can be described with an effective -symmetric Hamiltonian. This simple model allows the prediction of scattering resonance line shapes, validated up to , and close to the Toulouse point , where inelastic scattering becomes relevant. Our predictions model experiments with superconducting circuits [P. Forn-Díaz et al., Nat. Phys. 13, 39 (2017)] and can be extended to study multiphoton scattering.
