Fine structure in the off-resonance conductance of small Coulomb-blockade systems
Fine structure in the off-resonance conductance of small Coulomb-blockade systems
We show how a fine, multiple-peak structure can arise in the off-resonance, zero-bias conductance of Coulomb-blockade systems. In order to understand how this effect comes about one must abandon the orthodox, mean-field understanding of the Coulomb-blockade phenomenon and consider quantum fluctuations in the occupation of the single-particle electronic levels. We …
