Persistent Hall Voltage and Current in the Fractional Quantum Hall Regime
The persistent Hall voltage and current in an isolated annulus in a strong
perpendicular magnetic field, at odd inverse filling factor, and in the
presence of a weak constriction is obtained as a function of temperature, and
flux piercing the annulus. A thermodynamic Hall conductance is found which has
a universal value even with back scattering at the constriction. Included are
detailed appendices on the bosonization of chiral soliton operators and the
derivation of the chiral action, which has an additional topological term
originating from the dynamics of the zero modes.Comment: 12 pages, Late
