LPHON_DISPERSION = .TRUE. | .FALSE. 

Default: LPHON_DISPERSION = .FALSE.

Description: LPHON_DISPERSION requests the calculation of the phonon dispersion along the q-point path supplied in file QPOINTS (same format as KPOINTS).


After the computation of the force constants using finite differences (IBRION=5,6) or density-functional perturbation theory (IBRION=7,8) on a supercell it is possible to compute the phonon dispersion for the equivalent primitive cell determined by VASP by setting LPHON_DISPERSION=.TRUE.

Mind: Only available as of VASP 6.3.2.
