Abstract

A perturbation-theory formulation of the zero-temperature elastic constants is used to verify symmetry relations for a (monolayer) triangluar lattice. A generalization of the Cauchy relation between the two elastic constants of the triangular lattice with central-pair-potential interactions is given for the quantum solid. The first-order quantum corrections are rederived in this formalism, and previous calculations are reanalyzed.
