Nonequilibrium Transport through a Kondo Dot in a Magnetic Field: Perturbation Theory and Poor Man’s Scaling

Nonequilibrium Transport through a Kondo Dot in a Magnetic Field: Perturbation Theory and Poor Man’s Scaling

We consider electron transport through a quantum dot described by the Kondo model in the regime of large transport voltage V in the presence of a magnetic field B with max((V,B)>>T(K). The electric current I and the local magnetization M are found to be universal functions of V/T(K) and B/T(K), …
