摘要：

We investigate the statistical mechanics of a one-dimensional model with nearest-neighbor interactions and a substrate potential that exhibits an entropy-driven transition. Approximate analytical results obtained with the second-order self-consistent phonons method are presented. Two different numerical methods are used to derive exact numerical results for the thermodynamical functions. Finally, we discuss the important features of the Hamiltonian, which are responsible for this phase transition. © 1995 The American Physical Society.
