Modulation of the Kondo Effect in a Multi-ElectronQuantum Dot

摘要

We investigate a lateral semiconductor quantum dot with a large number ofelectrons in the limit of strong coupling to the leads. A Kondo effect showing the typicalfingerprints is observed. It can be tuned in a perpendicular magnetic field showing a highlyperiodic modulation with one flux quantum per dot area. This Kondo effect does not exhibitthe Zeeman splitting expected in a magnetic field.
