Quantum mechanics of several or many interacting identical or distinguishable degrees of freedom.

This is an authored directed relation from the source endpoint to the target endpoint.
Many-body quantum mechanics specializes quantum theory to interacting multi-degree systems.
A more specific theory, model, entity class, or regime is obtained by restricting or extending the scope of a broader framework.

A Slater determinant supplies a basic antisymmetric single-configuration ansatz within fermionic many-body quantum mechanics; it does not formulate the whole subject.
The source supplies a substantive formal ingredient, dynamical sector, law, field content, or mechanism of the target theoretical framework.

Composite distinguishable quantum systems use tensor-product Hilbert spaces, with symmetry restrictions for identical particles.
A mathematical concept supplies part of the formal language, state space, representation, or analytic machinery used by a scientific or mathematical-physics concept. The source is the mathematical predecessor; this does not claim that physical content follows from mathematics alone.

The state space of distinguishable composite quantum systems is modeled by a tensor product, with constraints for identical particles.

This is an authored directed relation from the source endpoint to the target endpoint.
Interacting and identical-particle many-body states generally exhibit correlations that can include entanglement relative to a chosen subsystem structure.
The target represents a state, property, observable, or state-dependent description associated with the source system or theory.

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.

Second quantization reformulates many-body states and operators in Fock space.
Reinterpret an object, pass to an equivalent presentation, or relate canonically corresponding structures; the carrier may change.
