HFHubbardLab is a theoretically inclined training on static mean-field (aka Hartree Fock) treatment of Hubbard models. Nevertheless some interesting numerical aspects arise as the stability of the self-consistency loop is concerned (mainly around first-order critical lines, where the loop may converge on metastable solutions). The correspondent preparatory course has been given by prof. Massimo Capone at SISSA.
The final report has been added for convenience. Everything is single authored here; nevertheless extremely useful discussions with Matteo Ferraretto, Guglielmo Lami, Nishan Ranabhat and Pietro Torta are gratefully acknowledged.
