Electron correlation effects on tunneling through a two-level quantum dot

摘要: The possibility of detection the Kondo effect by means measurement Bohm-Aharonov oscillations current going through a quantum dot embedded in one arms mesoscopic ring connected to two leads is demonstrated. threaded magnetic flux and subjected gate voltage V0 which controls its charge content. Whenever has an odd number electrons and, as consequence, net spin system regime. Thus, can be turned on off levels their associate Coulomb blockade peaks are tuned Fermi level changing V0. Since resonance provides new channel for tunnel it allows flowing along arm contains even though out resonance. interference between waves upper lower gives rise clear si...
