Statistically interacting vacancy particles

Abstract: The equilibrium statistical mechanics of one-dimensional lattice gases with interactions of arbitrary range and shape between first-neighbor atoms is solved exactly on the basis of statistically interacting vacancy particles. Two sets of vacancy particles are considered. In one set all vacancies are of one-cell size. In the other set the sizes of vacancy particles match the separation between atoms. Explicit expressions are obtained for the Gibbs free energy and the distribution of spaces between atoms at ther… Show more

“…For such cases an exact DFT calculation of density profiles tends to be be impracticable and calculations based on recursion relation for partition functions [9,12] are cumbersome. For long-range firstneighbor interactions, the SIVP method [10] provides a user-friendly way to derive the EOS.…”
