The phase diagram of the lattice Calogero-Sutherland model
arXiv:cond-mat/0012253 · doi:10.1103/PhysRevB.61.R10594
Abstract
We introduce a {\it lattice} version of the Calogero Sutherland model adapted to describe $1/d^2$ pairwise interacting steps with discrete positions on a vicinal surface. The configurational free energy is obtained within a transfer matrix method. The full phase diagram for attractive and for repulsive interaction is deduced. For attraction, critical temperatures of faceting transitions are found to depend on step density.
