Keldysh Functional Integral Theory of Non-equilibrium Kondo Bridge
Jung Hoon Han
We develop a consistent method for calculating non-equilibrium Green's functions for a nano-sized dot coupled to electron reservoirs by tunneling. The leads are generally at differ…

A New Mean-Field Theory of the Kondo Resonance at Finite Bias
Jung Hoon Han
We introduce a new slave-boson mean-field treatment of the Kondo effect in a quantum dot attached to the leads, when the bias voltage across the leads is finite. The model employs…
