Towards complete string effective actions beyond leading order

Kasper Peeters, Pierre Vanhove, Anders Westerberg

We review the current knowledge of higher-derivative terms in string effective actions, the various approaches that have been used to obtain them and their applications.

Boundary Ground Ring in 2D String Theory

Ivan K. Kostov

The 2D quantum gravity on a disc, or the non-critical theory of open strings, is known to exhibit an integrable structure, the boundary ground ring, which determines completely the…

Orthogonal Polynomials for Potentials of two Variables with External Sources

M. C. Bergère

This publication is an exercise which extends to two variables the Christoffel's construction of orthogonal polynomials for potentials of one variable with external sources. We gen…

Distributions of Dirac Operator Eigenvalues

G. Akemann, P. H. Damgaard

The distribution of individual Dirac eigenvalues is derived by relating them to the density and higher eigenvalue correlation functions. The relations are general and hold for any…

Polyakov Lines in Yang-Mills Matrix Models

Peter Austing, Graziano Vernizzi, John F. Wheater

We study the Polyakov line in Yang-Mills matrix models, which include the IKKT model of IIB string theory. For the gauge group SU(2) we give the exact formulae in the form of integ…

Branes in the 2D black hole

Sylvain Ribault, Volker Schomerus

We present a comprehensive analysis of branes in the Euclidean 2D black hole (cigar). In particular, exact boundary states and annulus amplitudes are provided for D0-branes which a…

Detuned Branes and Supersymmetry Breaking

Ph. Brax, N. Chatillon

We consider the spontaneous breaking of supersymmetry in five dimensional supergravity with boundaries where the supersymmetry breaking mechanism is provided by the even part of th…

On Minisuperspace Models of S-branes

Stefan Fredenhagen, Volker Schomerus

In this note we reconsider the minisuperspace toy models for rolling and bouncing tachyons. We show that the theories require to choose boundary conditions at infinity since partic…

String loop corrections to the universal hypermultiplet

Ignatios Antoniadis, Ruben Minasian, Stefan Theisen +1

We study loop corrections to the universal dilaton supermultiplet for type IIA strings compactified on Calabi-Yau threefolds. We show that the corresponding quaternionic kinetic te…

Boundary Liouville Theory and 2D Quantum Gravity

Ivan K. Kostov, Benedicte Ponsot, Didina Serban

We study the boundary correlation functions in Liouville theory and in solvable statistical models of 2D quantum gravity. In Liouville theory we derive functional identities for al…

Quantum Field Theory in the Large N Limit: a review

Moshe Moshe, Jean Zinn-Justin

We review the solutions of O(N) and U(N) quantum field theories in the large $N$ limit and as 1/N expansions, in the case of vector representations. Since invariant composite field…

Rolling Tachyons from Liouville theory

Volker Schomerus

In this work we propose an exact solution of the c=1 Liouville model, i.e. of the world-sheet theory that describes the homogeneous decay of a closed string tachyon. Our expression…

Universal random matrix correlations of ratios of characteristic polynomials at the spectral edges

G. Akemann, Y. V. Fyodorov

It has been shown recently [10] that Cauchy transforms of orthogonal polynomials appear naturally in general correlation functions containing ratios of characteristic polynomials o…

Cosmological constant and kinetic supersymmetry breakdown on a moving brane

Philippe Brax, Adam Falkowski, Zygmunt Lalak

We consider cosmological solutions in 5d locally supersymmetric theories including boundary actions, with either opposite tension branes for identical brane chiralities or equal te…

Mixed Correlation Functions of the Two-Matrix Model

M. Bertola, B. Eynard

We compute the correlation functions mixing the powers of two non-commuting random matrices within the same trace. The angular part of the integration was partially known in the li…

Cosmology and Brane Worlds: A Review

Philippe Brax, Carsten van de Bruck

Cosmological consequences of the brane world scenario are reviewed in a pedagogical manner. According to the brane world idea, the standard model particles are confined on a hyper-…

On the AdS/CFT Dual of Deconstruction

Ph. Brax, R. A. Janik, R. Peschanski

We consider a class of non-supersymmetric gauge theories obtained by orbifolding the N=4 super-Yang-Mills theories. We focus on the resulting quiver theories in their deconstructed…

Integrable quantum field theories with supergroup symmetries: the $O S P (1/2)$ case

Hubert Saleur, Birgit Wehefritz-Kaufmann

As a step to understand general patterns of integrability in 1+1 quantum field theories with supergroup symmetry, we study in details the case of $O S P (1/2)$ . Our results include th…
