Abstract
The effects of a long-range electronic potential on a one-dimensional commensurate charge-density-wave state are investigated. Using numeric al techniques it is shown that a transition to a metallic ground state is reached as the range of the electron-electron repulsion increases. In this metallic state, the optical conductivity exhibits a large Dru de weight. Possible interpretations of our results are discussed.
