Two-channel kondo effect

WebApr 10, 2024 · For the edge states with even stronger repulsive interactions, i.e. $1/4<1/2$, the system reaches another phase at low temperatures, described by a new two-channel Kondo fixed point. WebNov 25, 1996 · Abstract. We present a pedagogical and critical overview of the two-channel Kondo model and its possible relevance to a number of non-Fermi-liquid alloys and compounds. We survey the properties of the model, how a magnetic two-channel Kondo effect might obtain for ions in metals, and a quadrupolar Kondo effect for ions in metals.
