LSELFENERGY

LSELFENERGY = [logical]
Default: LSELFENERGY = .FALSE. 

Description: 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 $\langle \psi_{n {\mathbf{k}}} | \Sigma(\omega) |\psi_{n {\mathbf{k}}} \rangle$ is evaluated. QP shifts are printed to OUTCAR for low-scaling GW algorithms, otherwise the QP-calculation is bypassed.
