Abstract

Conductivity of a coupled two-channel dirty Tomonaga-Luttinger model is calculated from the Mori formalism. We find that the conductivity becomes enhanced as the interchannel interaction is turned on even when the interaction is repulsive. This effect is opposite to those from the 2KF charge-fluctuation coupling in systems with the channel separation <1/kF, and is considered to come from the suppressed charge-density-wave fluctuations.
