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 $\langle \phi_{n {\mathbf{k}}} | \Sigma(\omega) |\phi_{n {\mathbf{k}}} \rangle$ is evaluated. Evaluation of QP shifts is bypassed in this case.
