Description: Select whether to run and electron-phonon calculation.
| Mind: Available as of VASP 6.5.0 |
This flag determined whether an electron-phonon calculation should be performed. The most fundamental quantity we compute are the electron-phonon matrix elements.
These can simply be written to file when ELPH_DRIVER = MELS for further post-processing.
Additionally, one can directly use these matrix elements to compute the electron self-energy due to electron-phonon coupling ELPH_DRIVER = EL.
The self-energy can in turn be used to compute the renormalization of the electronic bandstructure or transport coefficients involving electron-phonon scattering.
Additionally, the tag ELPH_MODE sets defaults for other INCAR tags depending on the quantities of interest.
