RT Journal Article T1 Perturbation theory for the free energy of classical two-dimensional solids with repulsive inverse-power interactions A1 Cataldo, Horacio M. A1 Fernández Tejero, Carlos AB The free energy of classical two-dimensional solids with repulsive inverse-power interactions is obtained from a recently introduced perturbation theory. We obtain very accurate results for the thermodynamics of the solid phase as compared to the available simulation data.
