LSELFENERGY

LSELFENERGY = [logical]
Default: LSELFENERGY = .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 $\langle \psi _{n{\mathbf {k} }}|\Sigma (\omega )|\psi _{n{\mathbf {k} }}\rangle$ is evaluated. Evaluation of QP shifts is bypassed in this case.
