What Does GW Stand For?

GW stands for One Particle Green Function G Screened Coulomb Interaction W

GW refers to "One Particle Green Function G Screened Coulomb Interaction W," a pivotal method in many-body quantum physics used to compute electronic properties of materials. This technique combines the Green's function formalism with the perturbative treatment of electron-electron interactions, specifically focusing on the screening effects of the electron gas. By effectively accounting for these interactions, GW allows for accurate predictions of quasiparticle energies and enables a deeper understanding of electronic excitations in both fundamental and applied materials science contexts.
