- Abstract
- Linear conductance across a large quantum dot via a single level ?0 with large hybridization to the contacts is strongly sensitive to quasibound states localized in the dot and weakly coupled to ?0. The conductance oscillates with the gate voltage due to interference of the Fano type. At low temperature and Coulomb blockade, Kondo correlations damp the oscillations on an extended range of gate voltage values, by freezing the occupancy of the ?0 level itself. As a consequence, the antiresonances of Fano origin are washed out. The results are in good correspondence with experimental data for a large quantum dot in the semiopen regime. (literal)
