Welcome to the Green software package

Green is a software framework for the simulation of realistic materials with Green’s function methods. Green implements many-body methods including self-energy embedding, self-consistent GW, and second-order perturbation theory for solids and molecules. Green also provides a suite of post-processing and analysis tools.
