Non-linear sigma model — In quantum field theory, a nonlinear σ model describes a scalar field Σ which takes on values in a nonlinear manifold called the target manifold T. The target manifold is equipped with a Riemannian metric g. Σ is a differentiable map from… … Wikipedia
Chiral model — In nuclear physics, the chiral model is a phenomenological model describing mesons in the chiral limit where the masses of the quarks go to zero (without mentioning quarks at all). It s a nonlinear sigma model with the principal homogeneous space … Wikipedia
Nambu–Jona-Lasinio model — In quantum field theory, the Nambu–Jona Lasinio model (or more precisely: the Nambu and Jona Lasinio model) is a theory of nucleons and mesons constructed from interacting Dirac fermions with chiral symmetry which parallels the construction of… … Wikipedia
Wess-Zumino-Witten model — In theoretical physics and mathematics, the Wess Zumino Witten (WZW) model, also called the Wess Zumino Novikov Witten model, is a simple model of conformal field theory whose solutions are realized by affine Kac Moody algebras. It is named after … Wikipedia
Chern–Simons theory — The Chern–Simons theory is a 3 dimensional topological quantum field theory of Schwarz type, introduced by Edward Witten. It is so named because its action is proportional to the integral of the Chern–Simons 3 form. In condensed matter physics,… … Wikipedia

Supergravity — In theoretical physics, supergravity (supergravity theory) is a field theory that combines the principles of supersymmetry and general relativity. Together, these imply that, in supergravity, the supersymmetry is a local symmetry (in contrast to… … Wikipedia
Topological quantum field theory — A topological quantum field theory (or topological field theory or TQFT) is a quantum field theory which computes topological invariants.Although TQFTs were invented by physicists (notably Edward Witten), they are primarily of mathematical… … Wikipedia
