# Making use of self-energy functionals: The variational cluster approximation

@article{Potthoff2014MakingUO, title={Making use of self-energy functionals: The variational cluster approximation}, author={Michael Potthoff}, journal={arXiv: Strongly Correlated Electrons}, year={2014} }

A pedagogical introduction to the cluster-perturbation theory, the variational cluster approximation and to self-energy-functional theory is given. Some standard applications and the relation to dynamical mean-field theory are discussed.
