LVGVCALC = .TRUE. | .FALSE.
Default: LVGVCALC = .TRUE.
Description: LVGVCALC switches on calculation of the vGv expression for the orbital magnetic susceptibility.
LVGVCALC is available as of VASP.6.4.0.
When performing a chemical shift calculation the standard pGv susceptibility[1] is calculated and used in the calculation of the CSA tensor. When LVGVCALC is true, the magnetic susceptibility is also calculated with the vGv approximation. LVGVAPPL determines whether the vGv or pGv result is applied in the calculation of the contribution to the CSA tensor.
The vGv expression for the orbital susceptibility was introduced by d'Avezac et al.[2] In VASP its ultra-soft generalization is used.[3]
