Parameter: icu

Definition

Key control flag, determine the scheme to build the Coulomb interaction matrix.

Type

Integer

Default value

1

Component

Only for the JASMINE component.

Behavior

There are three possible values for the icu parameter.

• icu = 1, Kanamori scheme, using $U_c$, $U_v$, $J_z$, $J_s$, $J_p$ parameters, isotropic Hund's rule coupling.

• icu = 2, Slater-Cordon scheme, using $U_d$, $J_h$ parameters to build $F_0$, $F_2$, $F_4$, $F_6$.

• icu = 3, Kanamori scheme, using $U_c$, $U_v$, $J_z$, $J_s$, $J_p$ parameters, anisotropic Hund's rule coupling.

When icu = 2, it is not compatible with ictqmc = 4.
