A certain number of hybrid functionals are available in VASP, and furthermore if VASP was compiled with the library of exchange-correlation functionals Libxc, then most of the existing hybrid functionals can be used[1]. Examples of INCAR files are shown below for some of the most popular hybrid functionals.
- HSE06[2]
LHFCALC = .TRUE. GGA = PE HFSCREEN = 0.2
- with the default values AEXX=0.25, AGGAX=1-AEXX=0.75, AGGAC=1.0 and ALDAC=1.0, and using the PBE POTCAR files.
LHFCALC = .TRUE. GGA = PE HFSCREEN = 0.3
- with the default values AEXX=0.25, AGGAX=1-AEXX=0.75, AGGAC=1.0 and ALDAC=1.0, and using the PBE POTCAR files.
- HSEsol[6]
LHFCALC = .TRUE. GGA = PS HFSCREEN = 0.2
- with the default values AEXX=0.25, AGGAX=1-AEXX=0.75, AGGAC=1.0 and ALDAC=1.0, and using the PBE POTCAR files.
LHFCALC = .TRUE. GGA = PE
- with the default values AEXX=0.25, AGGAX=1-AEXX=0.75, AGGAC=1.0 and ALDAC=1.0, and using the PBE POTCAR files.
- B3PW91[10] (using Libxc)
LHFCALC = .TRUE. GGA = LIBXC LIBXC1 = 401 (or HYB_GGA_XC_B3PW91) AEXX = 0.2
- and using PBE POTCAR files.
- B3LYP[11] with VWN3 (or VWN5) for LDA correlation
LHFCALC = .TRUE. GGA = B3 (or B5) AEXX = 0.2 AGGAX = 0.72 AGGAC = 0.81 ALDAC = 0.19
- and using PBE POTCAR files.
- Hartree-Fock
LHFCALC = .TRUE. AEXX = 1.0 ALDAC = 0.0 AGGAC = 0.0
