Description
We show that electron transport in disordered quantum wires can be described by a modified Cooperon equation, which coincides in form with the Dirac equation for the massive fermions in a (1+1)-dimensional system. In this new formalism, we calculate the direct electric current induced by electromagnetic (EM) fields in quasi-one-dimensional rings. This current changes sign, from diamagnetic to paramagnetic, depending on the amplitude and frequency of the time-dependent external EM field. (author)
