A quantum system with many constituent degrees of freedom whose interactions and exchange statistics generally prevent reduction to independent one-particle solutions.

This is an authored directed relation from the source endpoint to the target endpoint.
Condensed-matter physics describes quantum many-body systems and their material, collective, and low-energy behavior.
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 quantum mechanics governs systems with several or many interacting quantum degrees of freedom; condensed-matter models select particular constituents, interactions, dimensionalities, and phases.
A theory, law, or interaction describes the behavior of the target within a stated regime. The edge detail must state important limits or qualifications.

This is an authored directed relation from the source endpoint to the target endpoint.
Correlated motion of many microscopic degrees of freedom can produce collective modes with effective dispersions and quantum numbers.
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.

Ordinary electronic condensed matter is a quantum many-body system of electrons and ionic cores or nuclei, commonly treated with effective low-energy degrees of freedom.
The target is a member or subtype of the broader source class.

In regimes with sufficiently weak damping, poles or coherent structures in the interacting system behave as quasiparticles with renormalized properties.
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.
