Energy and state-structure effects arising from antisymmetry of identical-fermion states; it is not an additional fundamental force.

This is an authored directed relation from the source endpoint to the target endpoint.
Antisymmetry produces exchange terms and selection effects without introducing a new force.
Record a genuine theorem implication that is not part of the target definition; these edges may point toward a weaker structure.

This is an authored directed relation from the source endpoint to the target endpoint.
Fermionic exchange and the resulting effective spin couplings are central microscopic contributions to many magnetically ordered phases. Exchange is not a separate force, and anisotropy, itinerancy, dipolar coupling, and lattice effects can also matter.
The source field, particle, charge, current, or interaction couples to, acts on, binds, forms, or stabilizes the target in the stated regime. The edge label and detail must identify the exact coupling, interaction, or binding claim and its qualifications.
