LSELFENERGY
KGAMMA = [logical]
Default: KGAMMA = .FALSE.
Description: This tag controls whether the frequency dependent self-energy is calculated or not.
If LSELFENERGY=.FALSE., QP shifts are evaluated. This is the default behavior.
If LSELFENERGY=.TRUE., the frequency dependent self-energy [math]\displaystyle{ \langle \phi_{n {\mathbf{k}}} | \Sigma(\omega) |\phi_{n {\mathbf{k}}} \rangle }[/math] is evaluated. Evaluation of QP shifts is bypassed in this case.
