List of quantum field theories

This is a list of quantum field theories. The first few sections are organized according to their matter content, that is, the types of fields appearing in the theory. This is just one of many ways to organize quantum field theories, but reflects the way the subject is taught pedagogically.

Scalar field theory
Theories whose matter content consists of only scalar fields
 * Klein-Gordon: free scalar field theory
 * φ4 theory
 * Sine-Gordon
 * Toda field theory

Spinor field theory
Theories whose matter content consists only of spinor fields
 * Dirac theory: free spinor field theory
 * Thirring model
 * Nambu–Jona-Lasinio model
 * Gross–Neveu model

Gauge field theory
Theories whose matter content consists only of gauge fields
 * Yang–Mills theory
 * Proca theory
 * Chern–Simons theory

Interacting theories

 * Spinor and scalar
 * Yukawa model
 * Scalar and gauge
 * Scalar electrodynamics
 * Scalar chromodynamics
 * Yang–Mills–Higgs
 * Spinor and gauge
 * Quantum electrodynamics (QED)
 * Schwinger model (1+1D case of QED)
 * Quantum chromodynamics (QCD)
 * Scalar, spinor and gauge
 * Standard Model

Sigma models

 * Chiral model
 * Non-linear sigma model
 * Wess–Zumino–Witten model

Supersymmetric quantum field theories

 * Wess–Zumino model
 * Supersymmetric Yang–Mills
 * Seiberg–Witten theory

Superconformal quantum field theories

 * N = 4 supersymmetric Yang–Mills theory

 * Nambu-Goto action
 * Bosonic string theory

Other quantum field theories

 * Kondo model (s-d model)
 * Minimal model (Virasoro minimal model)
