Title: Mesoscopic Kondo resonance in a quantum dot connected to an Aharonov-Bohni ring
Author: Kang, K
Craco, L
Abstract: Phase-sensitive transport through a quantum dot coupled to an Aharonov-Bohm ring is analyzed. In this geometry the spectral density of states is directly related to the conductance. It is shown that the Kondo resonance depends on the phase and on the total number of electrons (modulo 4) in the mesoscopic ring. The effect of the discrete level spacing in the ring and of the coupling to the electrical leads is discussed.
