LRHFCALC

From VASP Wiki

LRHFCALC = .TRUE. | .FALSE.
Default: LRHFCALC = .FALSE. 

Description: Switch on the decomposition of the exchange for the hybrid functionals using full Hartree-Fock exchange at long range, like RSHXLDA or RSHXPBE.


If LRHFCALC=.TRUE. the exchange functional is decomposed into short-range LDA, PBE or PBEsol (GGA=CA, PE, PS, respectively) and long-range Hartree-Fock, like for instance in RSHXLDA or RSHXPBE.[1][2][3] The screening parameter is specified by means of the HFSCREEN tag.

The setting of the RSHXLDA and RSHXPBE functionals is shown on the page listing the hybrid functionals.
