Study of Hund's rule coupling in models of magnetic impurities and quantum dots
Y. Nishikawa, A. C. Hewson
Studies of the effects of the Hund's rule coupling J_H in multiple orbit impurities or quantum dots using different models have led to quite different predictions for the Kondo tem…

Phase diagram and critical points of a double quantum dot
Y. Nishikawa, D. J. G. Crow, A. C. Hewson
We apply a combination of numerical renormalization group (NRG) and renormalized perturbation theory (RPT) to a model of two quantum dots (impurities) described by two Anderson imp…

Full counting statistics for orbital-degenerate impurity Anderson model with Hund's rule exchange coupling
Rui Sakano, Yunori Nishikawa, Akira Oguri +2
We study non-equilibrium current fluctuations through a quantum dot, which includes a ferromagnetic Hund's rule coupling , in the low-energy Fermi liquid regime using the renorm…
