ELPH_LR = [integer]
Default: ELPH_LR = 1 

Description: Controls the treatment of the long-range part of the electron-phonon potential.

Mind: Available as of VASP 6.5.0

This tag controls the treatment of the long-range electrostatic contributions to the electron-phonon coupling arising in polar dielectric materials.

Mind: In this case, the required Born effective charges and dielectric tensor are read from the phelel_params.hdf5 file.

Modes

ELPH_LR ≤ 0
No long-range correction scheme is applied to the electron-phonon coupling. This is most likely very inaccurate for semiconductors and insulators with non-vanishing Born effective charge.
ELPH_LR = 1
Dipole corrections are applied to the electron-phonon coupling[1].
