The 2-Channel Kondo model: II. CFT calculation of non-equilibrium conductance through a nanoconstriction containing 2-channel kondo impurities

Abstract

Recent experiments by Ralph and Buhrman on zero-bias anomalies in quenched Cu nanoconstrictions (reviewed in a preceding paper) are in accord with the assumption that the interaction between electrons and nearly degenerate two-level systems in the constriction can be described, for sufficiently small voltages and temperatures (V, T
