Codes
EPW
EPW is an open-source community code for ab initio calculations of electron-phonon interactions using Density-Functional Perturbation Theory and Maximally Localized Wannier Functions.
BerkeleyGW
BerkeleyGW is a many-body perturbation theory code for excited states, using the GW method and the GW plus Bethe-Salpeter equation (GW-BSE) method to solve respectively for quasiparticle excitations and optical properties of materials.
