Description

Currently the 1RDM in VMC/DMC is projected onto a single SPOSet as a basis. In the event that the basis corresponds to molecular/Bloch orbitals (typical case so far), use of a single basis for up and down electrons is likely to be a poor choice for spin-polarized systems.

Support is needed to handle separate bases for up and down electrons to appropriately cope with systems exhibiting local magnetic moments.
