Width of the charge-transfer peak in the SU(N) impurity Anderson model and its relevance to non-equilibrium transport

J. Fernández, F. Lisandrini, P. Roura-Bas +2

We calculate the width $2{\Delta }_{\text{CT}}$ and intensity of the charge-transfer peak (the one lying at the on-site energy $E_d$) in the impurity spectral density of states as a functi…
