The dependence of the shot noise suppression factor on the length of a mesoscopic cavity is investigated using numerical techniques based on the recursive Green's function approach and on the scattering matrix formalism. Our findings show that such a dependence disappears as soon as the magnetic field is raised above a threshold value and that there is no significant effect of the detailed behavior of the potential landscape inside the cavity.

Abstract
The dependence of the shot noise suppression factor on the length of a mesoscopic cavity is investigated using numerical techniques based on the recursive Green's function approach and on the scattering matrix formalism. Our findings show that such a dependence disappears as soon as the magnetic field is raised above a threshold value and that there is no significant effect of the detailed behavior of the potential landscape inside the cavity.File in questo prodotto:
