Gutzwiller variational embedding approach (equivalent to rotationally invariant slave-boson method at saddle-point approximation) to solve the ground state properties of a generic Hubbard model. Used with a python wrapper "pygrisb". It is a key component in ComRISB, a sub-package in Comsuite developed in the US DOE's Center for Computational Material Spectroscopy and Design at Brookhaven National Laboratory.
