# BerkeleyGW¶

The BerkeleyGW Package is a set of computer codes that calculates 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. The package takes as input the mean-field results from various electronic structure codes such as the Kohn-Sham DFT eigenvalues and eigenvectors computed with Quantum ESPRESSO, PARATEC, PARSEC, Octopus, Abinit, Siesta etc.

NERSC provides modules for BerkeleyGW.
