Kondo effect in quantum dots at high voltage: universality and scaling.
Rosch A, Kroha J, Wölfle P. Rosch A, et al. Phys Rev Lett. 2001 Oct 8;87(15):156802. doi: 10.1103/PhysRevLett.87.156802. Epub 2001 Sep 24. Phys Rev Lett. 2001. PMID: 11580717
We examine the properties of a dc-biased quantum dot in the Coulomb blockade regime. For voltages V that are large compared to the Kondo temperature T(K), the physics is governed by the scales V and gamma, where gamma approximately V/ln(2)(V/T(K)) is the nonequilibrium dec …

While an interchain coupling of strength J(perpendicular) leads to kappa(T) proportional to 1/J(perpendicular)2 as expected from simple golden-rule arguments, we obtain a much larger kappa(T) proportional to 1/J'4 for a weak next-nearest-neighbor interaction J'. Thi …

The first one appearing at low B is a characteristic dip located at muBB approximately kBT, that may arise from umklapp scattering. The second one is a plateaulike feature in the quantum critical regime, muB|B - Bc| < kBT, where Bc is the saturation field at T=0.
