摘要：
A renormalization method is used to study the conductance of a one-dimensional metal in the presence of a periodic potential. The approach of Horovitz, Bohr, Kosterlitz, and Shulz is generalized to the case in which this potential has many Fourier components; it is further modified to include the Pokrovsky-Talapov behavior near the insulating phase. The Luther-Emery line is shown to correspond to an invariant line of the renormalization equations in the strong-coupling regime, beyond the range of validity of the Kosterlitz pertubative renormalization group.
