A quantity whose equilibrium value distinguishes phases and often transforms under a broken symmetry. Local order parameters are powerful for symmetry-breaking transitions but are not universal descriptors of every phase transition.

This is an authored directed relation from the source endpoint to the target endpoint.
For transitions admitting an order-parameter description, its equilibrium value distinguishes phases and often encodes spontaneous symmetry breaking; some topological and other transitions require different descriptors.
The target represents a state, property, observable, or state-dependent description associated with the source system or theory.
