SCALEE: Difference between revisions

Latest revision as of 14:05, 16 October 2024

SCALEE = [real]
Default: SCALEE = 1

Description: This tag specifies the coupling parameter of the energies and forces between a fully interacting system and a reference system.

The tag SCALEE sets the coupling parameter $\lambda$ and hence controls the Hamiltonian of the calculation. By default SCALEE=1 and the scaling of the energies and forces via the coupling constant is internally skipped in the code. To enable the scaling SCALEE $\ne$ 1 has to be specified.

More information using this tag is given here.
