Conformal Invariance and Critical Phenomena (Theoretical and Mathematical Physics) th Edition by Malte Henkel (Author) ISBN Cited by: The history of critical phenomena goes back to the year when Andrews discovered the critical point of carbon dioxide, located at about 31°C and 73 atmospheres pressure.

In the neighborhood ofthis point the carbon dioxide was observed to become opalescent, that is, light is strongly scattered.

This book provides an introduction to conformal field theory and a review of its applications to critical phenomena in condensed-matter systems. After reviewing simple phase transitions and explaining the foundations of conformal invariance and the algebraic methods required, it proceeds to the explicit calculation of four-point correlators.

In two dimensions, for a wide class of models, it completely determines the correlation functions at the critical point, and yields the exact values of the surface critical exponents. They are related to the bulk exponents in a non-trivial way.

In the last chapter, conformal invariance was used to constrain the multipoint correlation functions of isotropic critical two-dimensional systems. Before following the field-theoretic developments. The use of the conformal symmetry is well appreciated in the literature, but the fact that all the scale invariant phenomena in dimension enjoy the conformal property relies on the deep structure of the renormalization group.

The outstanding question is whether this feature is specific to dimension or it holds in higher dimensions, too.

Critical phenomena arise in a wide variety of physical systems. Systematic subsequent developments have been leading to the scaling theories of critical phenomena and the renormalization group which allow a precise description of the close neighborhood of the critical.

dpi OCR. 1. Introduction. The theory of conformal invariance has provided considerable fundamental insight in critical phenomena by predicting spectra of critical exponents in two-dimensional models.Other interesting theoretical results follow from conformal mappings of correlation functions between models defined in different geometries.

Abstract: This is an introduction to conformal invariance and two-dimensional critical phenomena for graduate students and condensed-matter physicists. After explaining the algebraic foundations of conformal invariance, numerical methods and their application to the Ising, Potts, Ashkin-Teller and XY models, tricritical behaviour, the Yang-Lee singularity and the XXZ chain are presented.

BOOK EXCERPT: Conformal Invariance and String Theory is an account of the series of lectures held in Summer School regarding Conformal Invariance and String Theory in September The purpose of the lectures is to present the important problems and results in these two areas of theoretical physics.

The text is divided into two major parts. conformal invariance. We observe that the statistics of vorticity clusters are remarkably close to that of critical percolation, one of the simplest universality classes of critical phenomena. These results represent a key step in the unification of 2D physics within the framework of conformal symmetry.

History. The idea of scale transformations and scale invariance is old in physics: Scaling arguments were commonplace for the Pythagorean school, Euclid, and up to Galileo. They became popular again at the end of the 19th century, perhaps the first example being the idea of enhanced viscosity of Osborne Reynolds, as a way to explain turbulence.

The renormalization group was initially devised.A detailed consideration of ideal (random walk-type) chains near surfaces serves as a first orientation.

Much of the materials have not appeared previously in book form. This text is the first to give an introduction simultaneously to the renormalization group, short distance expansions and conformal invariance in critical systems with a surface.Questions • Is the connection with 2D classical systems peculiar to the QDM?

Conformal invariance in 2D? Central charge? • Is this quantum phase transition generic?, i.e. is it robust to local short range perturbations of the QDM? • Why this is not a first order transition (as naively expected)?

• QDM models are known to have columnar, plaquette and “staggered" phases.
