Abstract:

We investigate the dc response of a 1D disordered ring coupled to a reservoir and driven by a magnetic flux with a linear dependence on time. We identify two regimes: (i) A localized or large length L regime, characterized by a dc conductance, gdc, whose probability distribution P(gdc) is identical to the one exhibited by a 1D wire of the same length L and disorder strength placed in a two terminal Landauer setup and (ii) a multifloquet regime for small L and weak coupling to the reservoir, which exhibits large currents and conductances that can be gdc>1, in spite of the fact that the ring contains spinless electrons and a single electronic transmission channel. The crossover length between the multifloquet to the single-channel transport regime Lc is controlled by the coupling to the reservoir. © 2007 The American Physical Society.
