Comment on "The renormalized superperturbation theory (rSPT) approach to the Anderson model in and out of equilibrium"
Abstract
I present briefly some facts about nonequilibrium renormalized perturbation theory, correcting recent misleading statements in [E. Mu\~noz, F. Zamani, L. Merker, T. A. Costi, and S. Kirchner, Journal of Physics: Conf. Series 807, 092001 (2017)], and discuss some results of this work using rSPT at equilibrium.
