Automatic generation of vacuum amplitude many-body perturbation series

摘要

An algorithm and a computer program in Fortran 95 axe 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 result of a particular application, generation of LATEX code to draw the diagrams, is shown.
