摘要

We give a comprehensive introduction into an efficient numerical scheme for the minimisation of Gutzwiller energy functionals for multi-band Hubbard models. Our method covers all conceivable cases of Gutzwiller variational wave functions and has been used successfully in previous numerical studies.
