The differential conductance G S = ∂ I S /∂ V given by equation ( 3 ) for g s = g v = 2 (red line). It is well approximated by the affine approximation (equation 4 ), {G}_{S}=1.20(V/{V}_{C}-1)× 4{e}^{2}/h , with V C = 0.62 V S (black dashed line). The truncated (first-order perturbation) Schwinger conductance (blue dash-dotted line), {G}_{S}^{*}=4{g}_{s}{g}_{v}{e}^{2}/h(1+π {V}_{S}/V){e}^{-π {V}_{S}/V} (main text), substantially deviates from the full series (equation 3 ).
