Automatic generation of vacuum amplitude many-body perturbation series

Abstract

An algorithm and a computer program in Fortran 95 are presented which enumerate the Hugenholtz diagram representation of the many-body perturbation series for the ground state energy with a two-body interaction. The output is in a form suitable for post-processing such as automatic code generation. The results of a particular application, generation of LaTeX code to draw the diagrams, is shown.
