A conformal field theory (CFT) is a quantum field theory that is invariant under conformal transformations
A conformal field theory (CFT) is a quantum field theory that is invariant under conformal transformations. In two dimensions, there is an algebra of local conformal transformations, and conformal field theories can sometimes be exactly solved or classified. Conformal field theory has important applications to condensed matter physics, statistical mechanics, quantum statistical mechanics, and string theory.
A two-dimensional conformal field theory is a quantum field theory on a Euclidean two-dimensional space, that is invariant under local conformal transformations. In contrast to other types of conformal field theories, two-dimensional conformal field theories have symmetry algebras. In some cases, this allows them to be solved exactly, using the conformal bootstrap method.

conformal theory describing a critical system in the scaling regime. A classical example of an exactly solved two–dimensional critical system is the Ising model. Zamolodchikov and A. Zamolodchikov, Ann. Phys. The hamiltonian of the model reads.
