We study, using numerical simulations, the transport and noise properties both of a series of barriers and of cascaded constrictions, comparing our results with the conclusions of previous analyses. In particular, we point out the differences existing between the case in which the barriers or the constrictions are evenly spaced and the case in which they are randomly spaced, proposing possible explanations for the observed phenomena.

Abstract
We study, using numerical simulations, the transport and noise properties both of a series of barriers and of cascaded constrictions, comparing our results with the conclusions of previous analyses. In particular, we point out the differences existing between the case in which the barriers or the constrictions are evenly spaced and the case in which they are randomly spaced, proposing possible explanations for the observed phenomena.File in questo prodotto:
