triqs_modest.misc.sigma_to_data_idx()

Dispatched C++ function(s).

[1] (spin_kind: str {"Polarized", "NonPolarized", "NonColinear"}, sigma: int)
  -> int

Map a spin index to a data index.

The mapping depends on the spin kind:

• Polarized: \(\sigma \to \sigma\) (an object can have different values for different \(\sigma\)).

• NonPolarized: \(\sigma \to 0\) (an object is the same for both \(\sigma\), so only one copy is stored).

• NonCollinear: \(\sigma \to 0\) (\(\sigma\) is always 0).
