YAMBO is an open-source code released within the GPL licence implementing first-principles methods based on Green’s function theory to describe excited-state properties of realistic materials.These methods include the GW approximation, the Bethe-Salpeter equation (BSE), electron-phonon interaction and non-equilibrium Green’s function theory (NEGF).
YAMBO relies on previously computed ground-state properties and for this reason it is interfaced with other density functional theory (DFT) codes.

YAMBO is part of
