ELPH_SELFEN_FAN = .TRUE. | .FALSE.
Default: ELPH_SELFEN_FAN = .FALSE.
Description: Controls whether the Fan-Migdal contribution is included in the calculation of the phonon-induced electron self-energy.
The phonon-induced electron self-energy has two contributions at second order in perturbation theory, the Fan-Migdal self-energy and the real-valued Debye-Waller self-energy. ELPH_SELFEN_FAN controls the computation of the former, while the latter can be computed via ELPH_SELFEN_DW.
The result is reported individually for each self-energy accumulator in the vaspout.h5 file as
/results/electron_phonon/electrons/self_energy_1/selfen_fan
