EFFECTS OF TUNNELING THROUGH COUPLED SERIES ATTRACTORS IN A MESOSCOPIC SYSTEM

We report the effects of resonant tunneling through multi-coupled attr actors in series in a quantum nanosystem. We find that the multiple sp lit-conductance peaks arise from resonant tunneling through multiple n ondegenerate quasi-bound-states of the coupled attractors. We also sho w that the coupling can be tuned by modulating the strength of the att ractor, demonstrating that the separation of peak splitting in conduct ance decreases as the attractor strengths increase.
