LIBMBD_ALPHA = [real array]
Description: LIBMBD_ALPHA defines the free-atom polarizabilities (bohr) used in the Tkatchenko-Scheffler and Many-body dispersion energy methods as implemented in the library libMBD of many-body dispersion methods[1][2][3].
LIBMBD_ALPHA allows to set values for the free-atom polarizabilities (bohr) used in the Tkatchenko-Scheffler and Many-body dispersion energy methods as implemented in the library libMBD of many-body dispersion methods[1][2][3]. For each atom listed in the POSCAR file, a value has to be provided. The values are internally passed to the first column of the libMBD input free_values described at the page [4].
| Important: This feature is available from VASP.6.5.0 onwards that needs to be compiled with -DLIBMBD. |
libMBD is a separate library package that has to be downloaded[2] and compiled before VASP is compiled with the corresponding precompiler options and links to the libraries.
