LOCALIZED_BASIS = MLWF | BLOCH | LOCPROJ 

Description: Specifies which basis is used for Coulomb matrix elements in constrained random-phase approximation (cRPA) calculations.


This tag is effective for ALGO = CRPA[R] and ALGO = 2E4W and is ignored otherwise. The tag affects how NTARGET_STATES is interpreted. For instance

LOCALIZED_BASIS = BLOCH
NTARGET_STATES = 1 4 5 8 

evaluates the Coulomb matrix elements in the Bloch basis for band 1, 4, 5 and 8.

In contrast,

LOCALIZED_BASIS = MLWF
NTARGET_STATES = 1 4 5 8 

evaluates the Coulomb matrix elements in the Wannier basis for the states 1, 4, 5 and 8 defined in the INCAR file or read from the WANPROJ file.
