Abstract
We present an application of the ab initio many-body perturbation approach for structural properties of solids. The total energy is calculated from the Galitskii-Migdal formula with a model spectral function whose parameters are determined from the GW method. The scheme is applied to calculate the equilibrium lattice constant and bulk modulus of sodium and aluminum, with good agreement with experiments.
