description         GW/Bethe-Salpeter equation
long_description    BerkeleyGW is a set of computer codes that calculate the quasiparticle properties \
                    and the optical responses of a large variety of materials from bulk periodic crystals \
                    to nanostructures such as slabs, wires and molecules, using many-body perturbation theory.
