The ac conductance as a function of the ac frequency ω at ε0 - μ = Γ. (a) The total conductance when ΓL = ΓR and δμL = -δμR. The broken lines indicate the conductance in the presence of e-ph interaction with γ = 0.4Γ. ω0 = 2Γ, or 0.5Γ. The solid line is the 'bare' conductance G0, in the absence of e-ph interaction. (b) The additional conductance due to the e-ph interaction, Gint(ω) = GH(ω) + Gex(ω), for the same parameters as in (a).
