Crossover behavior in two-channel Kondo model with channel-symmetry breaking
Source abstract
Abstract
Abstract We study the two-channel Kondo model with channel asymmetry by means of the non-crossing approximation. By calculating the static susceptibility and the conductance, we find that the non-Fermi-liquid (NFL) state emerges for sufficiently small channel asymmetry at low temperatures. The crossover between the NFL state and the Fermi-liquid state is elucidated.
