vdw_alpha0_ref sets the reference atomic polarizability [math]\displaystyle{ \alpha_0 }[/math] for the Tkatchenko-Scheffler van der Waals correction method.
Summary
| Required/optional | Type | Accepted values | Default | See also |
|---|---|---|---|---|
| Optional if TurboGAP knows the defaults for the given species, mandatory otherwise | Real array with dimension n_species
|
Any real array with dimension n_species
|
TurboGAP will try to set defaults for known elements, 0. otherwise; TurboGAP will print a WARNING if it does not know any defaults. | van der Waals corrections, vdw_type, vdw_rcut, vdw_sr, vdw_d, vdw_c6_ref, vdw_r0_ref, species, n_species

Example
n_species = 2 species = H C vdw_type = "ts" vdw_rcut = 15. vdw_sr = 0.94 vdw_d = 20. vdw_c6_ref = 3.88 27.8 ! eV * Angstrom^6, one per species vdw_r0_ref = 1.64 1.9 ! Angstrom, one per species vdw_alpha0_ref = 0.667 1.778 ! Angstrom^3, one per species
