A change between macroscopic phases as control parameters vary. In equilibrium statistical mechanics an ideal sharp transition is represented by nonanalytic thermodynamic behavior in the thermodynamic limit; finite systems display rounded precursors.

This is an authored directed relation from the source endpoint to the target endpoint.
At equilibrium, chemical potentials of transferable components satisfy phase-coexistence conditions subject to mechanical and thermal constraints.
A theory, law, or interaction describes the behavior of the target within a stated regime. The edge detail must state important limits or qualifications.

Many-body interactions and entropy can collectively produce structural, magnetic, superconducting, and other phase transitions as external controls vary.
The target is a collective, organizational, or scale-dependent phenomenon of the source constituents and interactions; it is not a mere list or classical sum of constituents.

A sharp nonanalytic equilibrium phase transition requires an infinite-system limit under the usual regularity assumptions; finite systems can display rapid but analytic crossover and finite-size scaling.
The source supplies a substantive formal ingredient, dynamical sector, law, field content, or mechanism of the target theoretical framework.

This is an authored directed relation from the source endpoint to the target endpoint.
Critical phenomena are the scale-invariant fluctuation behavior associated with continuous phase transitions near a critical point.
The target is a member or subtype of the broader source class.

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.
