The One-Dimensional KDP Model in Statistical Mechanics

It is observed that the one-dimensional analog of the Slater KDP model provides a simple introduction to the study of strongly interacting systems and phase transitions as well as to recent research on two-dimensional KDP models. Although the first-order phase transition of the one-dimensional Slater model technically disappears when more realistic interaction strengths are taken into account, an anomalously large specific heat remains in the modified one-dimensional model.
