Transport properties of a multichannel Kondo dot in a magnetic field
arXiv:1202.4558 · doi:10.1103/PhysRevB.85.134413
Abstract
We study the nonequilibrium transport through a multichannel Kondo quantum dot in the presence of a magnetic field. We use the exact solution of the two-loop renormalization group equation to derive analytical results for the g factor, the spin relaxation rates, the magnetization, and the differential conductance. We show that the finite magnetization leads to a coupling between the conduction channels which manifests itself in additional features in the differential conductance.
