Frequency dependent GW calculations
Available as of VASP.5.X. For details on the implementation and use of the GW routines we recommend the following references: Ref. [1], [2], [3], [4].
Subsections
- ALGO for response functions and GW calculations
- LMAXFOCKAE
- NOMEGA, NOMEGAR number of frequency points
- LSPECTRAL: use the spectral method
- OMEGAMAX, OMEGATL and CSHIFT
- ENCUTGW energy cutoff for response function
- ENCUTGWSOFT soft cutoff for Coulomb kernel
- ODDONLYGW and EVENONLYGW: reducing the -grid for the response functions
- LSELFENERGY: the frequency dependent self energy
- LWAVE: selfconsistent GW
- G0W0 calculations: Recipe for GW calculations
- scGW calculations: Recipe for selfconsistent GW calculations
- GW0 calculations: Recipe for partially selfconsistent GW calculations
- DM calculations with GW routines: Determination of the frequency dependent dielectric matrix (DM) using the GW routines
- scGW0 caveat
