Multifloquet to single electronic channel transition in the transport properties of a resistive 1D driven disordered ring

Mostrar todas las versiones(2)

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...
