Luttinger liquid in quasi-one-dimensional conductors stabilized by impurities: Electronic structure and low-temperature conductivity

A new non-Fermi liquid state of quasi-one-dimensional conductors is suggested in which electronic system exists in a form of collection of bounded Luttinger liquids stabilized by impurities towards inter-chain electron hopping at low temperatures. Mechanism of conductivity at low temperatures is phonon-assisted hopping via zero-mode states. At higher voltages conductivity obeys power-law dependence on voltage. The results provide a qualitative explanation of recent experimental data for NbSe3 and TaS3 crystals.
