TL;DR: In this article, a selfconsistent numerical approach was used to investigate the crossover from the Peierls-gap to the electron-gap with increasing intrasite electron-electron interaction.
Abstract: A selfconsistent numerical approach, which allows each (CH)-group in a finite polyacetylene chain to relax to its equilibrium position, is used to investigate the crossover from the Peierls-gap to the electron-gap with increasing intrasite electron-electron interaction. The dependence of the crossover on the electron-phonon coupling constant is also examined.
