The present volume is an extended and up-to-date version of two sets of lectures by the first author and it reviews more recent work. The notes aim to present a self-contained exposition of a constructive approach to conformal invariant quantum field by:   The properties of a field theory in one over-all time dimension, invariant under the full conformal group, are studied in detail.

A compact operator, which is not the Hamiltonian, is diagonalized and used to solve the problem of motion, providing a discrete spectrum and normalizable eigenstates. The role of the physical parameters present in the model is Cited by: COVID Resources.

We begin with some examples of classical conformal invariance, before moving on to talk about CFTs in critical phenomena and the renormalization group.

We brie y mention some applications of CFTs toward other subjects before nishing the lecture by discussing conformal quantum mechanics|conformal eld theory in d= 1 dimension.

NATO Advanced Study Institutes Series (Series B: Physics), vol by: Scale invariance is a weaker form of conformal invariance, and it turns out in all cases that we know of (or at least the ones I know of) scale invariance of a quantum field theory actually ends up implying the larger symmetry of conformal invariance.

So, if you care about a field theory near a phase transition or at the fixed point of an RG. Filling an important gap in the literature, this comprehensive text develops conformal field theory from first principles.

I would recommend the book Introduction to Conformal Field theory by Blumenhagen and Plauschinn. It is quite sort and can serve as a perfect introduction to CFT. It covers the basics of CFT in the first 3 chapters and then in the remaining 3 it goes on to introduce the CFT concepts that will appear most frequently in String theory.

The notes aim to present a self-contained exposition of a constructive approach to conformal invariant quantum field. A conformal field theory (CFT) is accordingly a functor on such a richer category of conformal cobordisms.

See the discussion at FQFT for more details. The conformally invariant quantum field theories have fields for whom the correlation functions have a specific behaviour accounting for the conformal dimension of the fields. The renormalizable quantum gravity introduced in this book offers a theory in which such a world is described by a certain conformal field theory and a deviation from there is handled as a perturbation.

Indeed, with each Kac-Moody algebra there is a Virasoro algebra associated in a natural way so that together they form a semi-direct product.

For example, in the WZW models, the currents realize 2 Kac-Moody algebras, and the components of the stress-tensor close into 2 Virasoro algebras; this is true in any 2D conformal field theory. Scale and Conformal Invariance in Quantum Field Theory.

The dictionary answer is that a conformal field theory is a theory that is invariant under conformal transformations. D'uh, you knew that already. OK, what is a conformal transformation. These are "angle-preserving" transformations in Euclidean. Conformal Field Theory () Course Description.

Quantum field theories fall into roughly two classes: "gapped" theories (where excited states are separated from the vacuum by an energy gap) and gapless theories. In gapped theories, correlations fall off exponentially with distance, so gapped theories are "almost trivial" at long distances.

Cardy, “Conformal invariance and statistical mechanics,” Les Houches Summer School.

Indeed, Topological Quantum Field Theory at its ground state has no scales (thus scale invariance) and it is also Poincaré (translations + Lorentz) invariance, and also have a special conformal transformation (if needed).The invariance under conformal transformations is a remnant of the invariance under a reparameterisation of the string: it is only the movement in the target space-time that counts, and not the way we describe it.

One can go one step further: it is only the conformal field theory that counts, and not its geometric interpretation.
