Logarithmic conformal field theories and strings in changing backgrounds

I review a particular class of physical applications of Logarithmic Conformal Field Theory in strings propagating in changing (not necessarily conformal) backgrounds, namely D-brane recoil in flat or

Extended multiplet structure in Logarithmic Conformal Field Theories

We use the process of quantum hamiltonian reduction of SU(2)k, at rational level k, to study explicitly the correlators of the h1,s fields in the cp,q models. We find from direct calculation of the

Conformal Field Theory Between Supersymmetry and Indecomposable Structures

This thesis considers conformal field theory in its supersymmetric extension as well as in its relaxation to logarithmic conformal field theory. Compactification of superstring theory on

Analytic bootstrap for logarithmic CFT

Abstract We study logarithmic conformal field theory (LogCFT) in four dimensions using conformal bootstrap techniques in the large spin limit. We focus on the constraints imposed by conformal

PP-wave string interactions from perturbative Yang-Mills theory

Recently, Berenstein et al. have proposed a duality between a sector of = 4 super-Yang-Mills theory with large R-charge J, and string theory in a pp-wave background. In the limit considered, the

Extended chiral algebras and the emergence of SU(2) quantum numbers in the Coulomb gas

We study a set of chiral symmetries contained in degenerate operators beyond the `minimal' sector of the cp,q models. For the operators h(2j+2)q−1,1 = h1,(2j+2)p−1 at conformal weight

Logarithmic torus amplitudes

AbstractFor the example of the logarithmic triplet theory at c = −2 the chiral vacuumtorus amplitudes are analysed. It is found that the space of these torus amplitudes isspanned by the characters of

An exact conformal field theory describing a black hole in two-dimensional space-time is found as an SL(2,{ital openR})/U(1) gauged Wess-Zumino-Witten model, which should be regarded as an analog of the extreme Reissner-Nordstroem black hole of four-dimensional general relativity.

Plane wave limits and T-duality

Non-compact WZW conformal field theories

We discuss non-compact WZW sigma models, especially the ones with symmetric space H C /H as the target, for H a compact Lie group. They offer examples of non-rational conformal field theories. We

On the logarithmic behaviour in = 4 SYM theory

We show that the logarithmic behaviour seen in perturbative and non perturbative contributions to Green functions of gauge-invariant composite operators in = 4 SYM with SU(N) gauge group can be

Families of exact (0,2) supersymmetric conformal field theories of magnetically and electrically charged extremal 4D black hole solutions of heterotic string theory are presented and an example of an extremal dilatonic Taub-NUT-like dyon is studied in detail.
