The waveguide dispersion (solid blue curve) is approximated as being linear (solid red lines) near the wave numbers±k0 corresponding to the frequencyω0. We eliminate the frequencyω0 using the transformation H→H−ω 0NE, where NE =σ +σ− + Z ∞ 0 a† R(k)aR(k)dk+ Z 0 −∞ a† L(k)aL(k)dk (5) is the total excitation number operator. This transforma- tion is simply a constant energy shift that does not affect the dynamics of the system becauseNE is a conserved quantity (i.e.,[H, N E] = 0). We absorb the remaining factor ofω 0 into the transition frequency of the emitter by definingω e = ˜ωe −ω 0. After the linearization, we extend the integration lim-"}],"limit":50,"offset":0}
