Abstract From a lattice model one may obtain a field theory by taking a continuum or scaling limit; letting the lattice spacing ε → 0, whilst simultaneously approaching the critical temperature. As the scale or correlation length becomes infinite one obtains a scale invariant or conformal invariant theory.

Conformal Field Theory (CFT) became a general technique in quantum field theory and its applications. One could say, in a sense, that for the critical phenomena in 2D statistical systems, and also for the string theory, the CFT plays the role similar to that which quantum mechanics plays for atomic physics.

Abstract In the previous chapters we have seen that, coming close to a critical point, the correlation length of a statistical system diverges and consequently there are influctuations on all possible scales. In such a regime, the properties of the statistical systems can be efficiently described by a quantum field theory.

Introduction to Conformal Field Theory
Fortschritte der Physik/Progress of Physics, 1996Summary: An elementary introduction to conformal field theory is given. Topics include free bosons and fermions, orbifolds, affine Lie algebras, coset conformal field theories, superconformal theories, correlation functions on the sphere, partition functions and modular invariance.

Conformal Field Theory III: Superconformal Field Theory
2012In Chap. 4 we have demonstrated the usefulness of conformal field theory as a tool for the bosonic string. In the same way as conformal symmetry was a remnant of the reparametrization invariance of the bosonic string in conformal gauge, superconformal invariance is a remnant of local supersymmetry of the fermionic string in super-conformal gauge.

TOPICS IN CONFORMAL FIELD THEORY
2014In this work two major topics in Conformal Field Theory are discussed. First a detailed investigation of N=2 Superconformal theories is presented. The structure of the representations of the N=2 superconformal algebras is investigated and the character formulae are calculated.
