Numerical minimisation of Gutzwiller energy functionals
arXiv:1111.4112 · doi:10.1002/pssb.201147585
Abstract
We give a comprehensive introduction into an efficient numerical scheme for the minimisation of Gutzwiller energy functionals in studies on multi-band Hubbard models. Our method covers all conceivable cases of Gutzwiller variational wave functions and has been used successfully in previous numerical studies.
