Resonant Transmission through a Quantum Dot in the Coulomb Blockade Regime

Abstract

We carry out an exact calculation of the transmission of electrons through a quantum dot in the Coulomb blockade regime for both degenerate and nondegenerate cases. We show that the intrinsic interference among the paths produced by the states of the dot causes the phase coherence of adjacent resonant peaks. The expression of conductance obtained in the degenerate case reproduces the main features of a dot in the Kondo regime.
