Current and Shot Noise in a Quantum Dot Coupled to Ferromagnetic Leads in the Kondo Regime

摘要

@@ Using the Keldysh nonequilibrium Green function technique, we study the current and shot noise spectroscopy of an interacting quantum dot coupled to two ferromagnetic leads with different polarizations in the Kondo regime.General formulas of current and shot noise are obtained, which can be applied in both the parallel (P) and antiparallel (AP) alignment cases.
