Query: Metal-insulator transition in a sliding Luttinger liquid with line
  defects   We investigate the effect of both strong and weak potential scattering caused
by local impurities and extended (line) defects in the array of Luttinger
liquid wires. We find that in both cases a finite range inter-wire interaction
stabilises metallic state. Based on calculation of the scaling dimensions of
one-particle scattering operators, we construct the phase diagram for
low-temperature transport along the array. We find that unlike local impurity
case where only conducting and insulating states are realised (metal-insulator
transition driven by interactions), the extended line defects may bring the
system into a mixed state where conducting or insulating behavior can be
observed depending on bare strength of the scatterer (metal-insulator
transition driven by disorder).
