TDependence of the Conductance in Quasi One-Dimensional Systems

We present a theory of the temperature-dependent conductance $G\mathrm{}\left(T\right)\mathrm{}$ of one-dimensional systems which depends only on the general principles of quantum resonance. Resonant and nonresonant conductances and temperature parameters $T_0$ are found to be related in a way which is in qualitative agreement with recent experiments. A new low-temperature regime is predicted in which $G\mathrm{}\left(T\right)\mathrm{}$ should change abruptly from Mott type to $T$ independent or metallic.
