Summary

The study of matter with many interacting degrees of freedom in condensed phases, emphasizing collective behavior, material properties, phases, and emergent quasiparticles rather than only isolated constituents.

Equilibrium thermodynamicsCondensed-matter physics

Permalink to relation

This is an authored directed relation from the source endpoint to the target endpoint.

Authored explanation

Equilibrium thermodynamics supplies state variables, potentials, stability criteria, and phase coexistence conditions for macroscopic materials.

How to interpret this relation type

The source supplies a substantive formal ingredient, dynamical sector, law, field content, or mechanism of the target theoretical framework.

Quantum field theoryCondensed-matter physics

Permalink to relation

This is an authored directed relation from the source endpoint to the target endpoint.

Authored explanation

Nonrelativistic quantum-field and many-body operator methods describe variable occupation, collective modes, symmetry breaking, and low-energy excitations in condensed matter. Condensed-matter physics also uses methods not organized as relativistic QFT.

This is an authored directed relation from the source endpoint to the target endpoint.

Authored explanation

Statistical mechanics supplies the ensemble, fluctuation, and phase-transition framework used throughout condensed-matter physics.

Condensed-matter physicsElectronic condensed-matter system

Permalink to relation

This is an authored directed relation from the source endpoint to the target endpoint.

Authored explanation

Electronic condensed matter is a central class of systems studied using quantum mechanics, statistical mechanics, electromagnetism, and material-specific structure.

How to interpret this relation type

A theory, law, or interaction describes the behavior of the target within a stated regime. The edge detail must state important limits or qualifications.
