DMFT_BASIS = MLWF | BLOCH | LOCPROJ
Description: Specifies which basis is used for Coulomb matrix elements in 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
DMFT_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,
DMFT_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.
