Abstract
The structure of one-dimensional systems as a function of temperature is investigated. Introduction of an intramonomer distortion coordinate in addition to the usual lattice coordinate induces up to two-phase transitions besides the usual Peierls transition. The impact of these additional phase transitions on the specific heat, energy gap, and lattice structure is discussed.Keywords
