Strongly Coupled One-Dimensional System and the Polymer
Abstract
What is the effect of the electron interaction on the lattice instability of one-dimensional systems with strong electron correlation is a controversial problem. One side believes the electron interaction enhances the instability; but the other side declares the instability is reduced by the electron interaction. The origin of this controversy is analyzed in this paper, and we find that the range of the electron interaction plays a decisive role. When the range is long, the electron interaction enhances the lattices instability, whereas, if the range is short, the electron interaction reduces the instability. Based on this conclusion, we can clarify the dispute about the effect of the electron interaction on the dimerization of the conducting polymers. (AW)
