Abstract

Perturbation theory and Monte Carlo simulation are applied to the study of low-temperature properties of a triangular phantom network of harmonic springs with nonzero resting length. We determine the equation of state and elastic moduli in the solid (ordered) phase, as well as the location of the solid-liquid phase boundary. A simple explanation is given for negative thermal expansivity. Agreement between two-loop perturbative results and simulation is fairly good, the largest discrepancies being in the location of the phase boundary. An expansion in inverse area, useful for the ordered phase, is also given.
