eminus.xc.lda_x.lda_x_spin(n, zeta, **kwargs)[source]#

Slater exchange functional (spin-polarized).

Corresponds to the functional with the label LDA_X and ID 1 in Libxc.

Reference: Phys. Rev. 81, 385.

Parameters:

  • n (ndarray) – Real-space electronic density.

  • zeta (ndarray) – Relative spin polarization.

Keyword Arguments:

**kwargs – Throwaway arguments.

Returns:

tuple[ndarray, ndarray] – Exchange energy density and potential.
