"Poor man's scaling: Kondo and CoqblinSchrieffer models"Who: Eugene Kogan, BarIlan University, Israel Place: Donostia International Physics Center Date: Friday, 23 February 2018, 12:00 We derive the general scaling equation to the second order for a model, describing any point scatterer, with degenerate energy levels, embedded into a gas of itinerant electrons. We show how the obtained previously scaling equations for spinanisotropic Kondo model follow from it. We introduce the notion of the anisotropic Coqblin?Schrieffer model. We apply the general equation to derive scaling equation for that model and integrate analytically the important particular case of that equation. https://arxiv.org/abs/1801.05233
