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. Evaluation of QP shifts is bypassed in this case.
