Available as of VASP.5.X. For details on the implementation and use of the GW routines we recommend the papers by Shishkin et al.[1][2][3] and Fuchs et al.[4]
Recipes
- G0W0 calculations: single-shot G0W0 calculations
- GW0, GW calculations: selfconsistent with respect to QP energies in G (GW0 calculations) or G AND W (GW calculations)
- scGW0, scGW calculations: selfconsistent with respect to QP energies AND orbitals in G (scGW0 calculations) or G AND W (scGW calculations)
- DM calculations with GW routines: Determination of the frequency dependent dielectric matrix (DM) using the GW routines
- scGW0 caveat
