ESF SPLINES
ESF_SPLINES = .FALSE. | .TRUE.
Default: ESF_SPLINES = .FALSE.
Description: ESF_SPLINES selects k-point interpolation in ACFDT(R) calculations using tri-cubic splines.
Interpolates the electronic structure factor in ACFDT/RPA calculations using tri-cubic splines to accelerate k-point convergence of the RPA correlation energy. This feature follows the same idea as in coupled cluster calculations.[1]
