WebJul 1, 1999 · We study numerically the influence of momentum-conserving dephasing on transport in a disordered chain of scatterers. Loss of phase memory is caused by coupling the transport channels to dephasing reservoirs. In contrast to previously used models, the dephasing reservoirs are linked to the transport channels between the scatterers, and …
