Abstract

The thermodynamic characteristics of a one-dimensional generalized Wigner crystal are investigated for arbitrary temperature, particle density, and character of the interparticle repulsive pair potential. A method is proposed which permits calculating the partition function of the system with allowance for the interaction between an arbitrary number of neighboring particles. It is shown that increasing this number leads to the appearance of increasingly fine steps in the low-temperature dependence of the particle density on the chemical potential. These steps are remnants of a dependence of the “devil’s staircase” type that is characteristic for this sort of system at zero temperature.
