  We study the electrical and thermal transport through the SU(N) Wolff model
with the use of bosonization. The Wilson ratio reaches unity as N grows to
infinity. The electric conductance is dominated by the charge channel, and
decreases monotonically with increasing interaction. The thermal conductivity
enhances in the presence of local Hubbard U. The Wiedemann-Franz law is
violated, the Lorentz number depends strongly on the interaction parameter,
which can be regarded as a manifestation of spin-charge separation.
