Fractional Charge in Transport Through a 1D Correlated Insulator of Finite Length

Abstract

Transport between two Fermi liquid reservoirs through a one channel wire of length L is examined when the ID electron system has an energy gap 2M: M > T(L) v(c) /L induced by the interaction in its charge mode (v(c)): charge velocity in the wire). In the spinless case transformation of reservoir electrons into solitons of fractional charge entails a crossover from a Fermi liquid regime of integer charge transfer below the crossover energy T(x) << T(L) to the insulating one of the fractional charge transfer in the current vs voltage, conductance vs temperature, and the shot noise. Similar behavior is predicted for a spin Mott insulator of filling factor v = n/ (2m') (n, m': positive integer).
