Aharonov-Bohm Oscillations and Resonant Tunneling in Strongly Correlated Quantum Dots
Aharonov-Bohm Oscillations and Resonant Tunneling in Strongly Correlated Quantum Dots
We investigate Aharonov-Bohm oscillations of the current through a strongly correlated quantum dot embedded in an arbitrary scattering geometry. Resonant-tunneling processes lead to a flux-dependent renormalization of the dot level. As a consequence, we obtain a fine structure of the current oscillations, which is controlled by quantum fluctuations. Strong Coulomb …
