One-Loop QCD Spin Chain and its Spectrum
N. Beisert, G. Ferretti, R. Heise +1
We study the renormalization of gauge invariant operators in large Nc QCD. We compute the complete matrix of anomalous dimensions to leading order in the 't Hooft coupling and stud…
Asymptotic degeneracy of dyonic N=4 string states and black hole entropy
G. L. Cardoso, B. de Wit, J. Käppeli +1
It is shown that the asymptotic growth of the microscopic degeneracy of BPS dyons in four-dimensional N=4 string theory captures the known corrections to the macroscopic entropy of…
The Factorized S-Matrix of CFT/AdS
Matthias Staudacher
We argue that the recently discovered integrability in the large-N CFT/AdS system is equivalent to diffractionless scattering of the corresponding hidden elementary excitations. Th…
On characteristic initial data for a star orbiting a black hole
Nigel T. Bishop, Roberto Gomez, Luis Lehner +2
We take further steps in the development of the characteristic approach to enable handling the physical problem of a compact self-gravitating object, such as a neutron star, in clo…
The 3-dimensional Einstein-Klein-Gordon system in characteristic numerical relativity
W. Barreto, A. Da Silva, R. Gomez +3
We incorporate a massless scalar field into a 3-dimensional code for the characteristic evolution of the gravitational field. The extended 3-dimensional code for the Einstein--Klei…
On the existence of initial data containing isolated black holes
Sergio Dain, Jose Luis Jaramillo, Badri Krishnan
We present a general construction of initial data for Einstein's equations containing an arbitrary number of black holes, each of which is instantaneously in equilibrium. Each blac…
Holographic dynamics of unstable branes in AdS
Marija Zamaklar, Kasper Peeters
The gauge theory dual to the decay of an unstable D-particle in AdS is analysed in terms of coherent states. We discuss in detail how to count the number of particles in the decay…
Quantum Strings and Bethe Equations
G. Arutyunov
I briefly review the recently proposed construction of the Bethe ansatz which diagonalizes the Hamiltonian for quantum strings on AdS_5\times S^5 at large tension and restricted to…
Planar plane-wave matrix theory at the four loop order: Integrability without BMN scaling
Thomas Fischbacher, Thomas Klose, Jan Plefka
We study SU(N) plane-wave matrix theory up to fourth perturbative order in its large N planar limit. The effective Hamiltonian in the closed su(2) subsector of the model is explici…
TFT construction of RCFT correlators IV: Structure constants and correlation functions
Jürgen Fuchs, Ingo Runkel, Christoph Schweigert
We compute the fundamental correlation functions in two-dimensional rational conformal field theory, from which all other correlators can be obtained by sewing: the correlators of…
Chern-Simons Theory, 2d Yang-Mills, and Lie Algebra Wanderers
Sebastian de Haro
We work out the relation between Chern-Simons, 2d Yang-Mills on the cylinder, and Brownian motion. We show that for the unitary, orthogonal and symplectic groups, various observabl…
Mechanics of multidimensional isolated horizons
M. Korzynski, J. Lewandowski, T. Pawlowski
Recently a multidimensional generalization of Isolated Horizon framework has been proposed by Lewandowski and Pawlowski (gr-qc/0410146). Therein the geometric description was easil…
Modeling the Black Hole Excision Problem
B. Szilagyi, H-O. Kreiss, J. Winicour
We analyze the excision strategy for simulating black holes. The problem is modeled by the propagation of quasi-linear waves in a 1-dimensional spatial region with timelike outer b…
One loop photon-graviton mixing in an electromagnetic field: Part 1
Fiorenzo Bastianelli, Christian Schubert
Photon-graviton mixing in an electromagnetic field is a process of potential interest for cosmology and astrophysics. At the tree level it has been studied by many authors. We cons…
Anisotropies in the Neutrino Fluxes and Heating Profiles in Two-dimensional, Time-dependent, Multi-group Radiation Hydrodynamics Simulations of Rotating Core-Collapse Supernovae
R. Walder, A. Burrows, C. D. Ott +3
Using the 2D multi-group, flux-limited diffusion version of the code VULCAN/2D, that also incorporates rotation, we have calculated the collapse, bounce, shock formation, and early…

Testing the Master Constraint Programme for Loop Quantum Gravity I. General Framework
Bianca Dittrich, Thomas Thiemann
Recently the Master Constraint Programme for Loop Quantum Gravity (LQG) was proposed as a classically equivalent way to impose the infinite number of Wheeler -- DeWitt constraint e…
IIB supergravity and E10
Axel Kleinschmidt, Hermann Nicolai
We analyse the geodesic E10/K(E10) sigma-model in a level decomposition w.r.t. the A8xA1 subalgebra of E10, adapted to the bosonic sector of type IIB supergravity, whose SL(2,R) sy…
Picard groups in rational conformal field theory
Jürg Fröhlich, Jürgen Fuchs, Ingo Runkel +1
Algebra and representation theory in modular tensor categories can be combined with tools from topological field theory to obtain a deeper understanding of rational conformal field…

Martin Bojowald, Hugo A. Morales-Tecotl, Hanno Sahlmann
A simple model is constructed which allows to compute modified dispersion relations with effects from loop quantum gravity. Different quantization choices can be realized and their…
