Functions

get_exc	Get the exchange-correlation energy density.
get_vxc	Get the exchange-correlation potential.
get_xc	Handle and get exchange-correlation functionals.

get_zeta	Calculate the relative spin polarization.
mock_xc	Mock exchange-correlation functional with no effect (spin-paired).
parse_functionals	Parse exchange-correlation functional strings to the internal format.
parse_xc_libxc	Parse functional type by its ID using pylibxc.
parse_xc_pyscf	Parse functional type by its ID using PySCF.
parse_xc_type	Parse functional strings to identify the corresponding functional type.
