ELPH SELFEN WRANGE

ELPH_SELFEN_WRANGE = [real]
Default: ELPH_SELFEN_WRANGE = 0 

Description: Together with ELPH_SELFEN_NW specifies the energy window in which to evaluate the phonon-induced electron self-energy.

---

The electron self-energy, $\Sigma_{n \mathbf{k}}(\omega)$, depends on the frequency $\omega$ (or energy $\hbar \omega$). The tag ELPH_SELFEN_WRANGE determines the width of the energy window in which to evaluate the self-energy. However, the location and width of the energy window is also influenced by the sign of ELPH_SELFEN_NW. For more information, we refer to the documentation of ELPH_SELFEN_NW.
