Dynamical Evolution of Boson Stars II: Excited States and Self-Interacting Fields
Jayashree Balakrishna, Edward Seidel, Wai-Mo Suen
The dynamical evolution of self-gravitating scalar field configurations in numerical relativity is studied. The previous analysis on ground state boson stars of non-interacting fie…
New Coordinate Systems for Axisymmetric Black Hole Collisions
P. Anninos, S. R. Brandt, P. Walker
We describe a grid generation procedure designed to construct new classes of orthogonal coordinate systems for binary black hole spacetimes. The computed coordinates offer an alter…
Self-consistent solutions for low-frequency gravitational background radiation
G. Dautcourt
We study in a Brill-Hartle type of approximation the back-reaction of a superposition of linear gravitational waves in an Einstein-de Sitter background up to the second order in th…
Cosmic-String-Seeded Structure Formation
P. P. Avelino, E. P. S. Shellard, J. H. P. Wu +1
We describe the results of high-resolution numerical simulations of string-induced structure formation in open universes and those with a non-zero cosmological constant. For models…
Towards gravitational-wave asteroseismology
Nils Andersson, Kostas D. Kokkotas
We present new results for pulsating neutron stars. We have calculated the eigenfrequencies of the modes that one would expect to be the most important gravitational-wave sources:…
A Note on the Geometry of CHL Heterotic Strings
W. Lerche, R. Minasian, C. Schweigert +1
We present a few remarks on disconnected components of the moduli space of heterotic string compactifications on . We show in particular how the eight dimensional CHL heteroti…
Quantum Theory of Geometry II: Volume operators
Abhay Ashtekar, Jerzy Lewandowski
A functional calculus on the space of (generalized) connections was recently introduced without any reference to a background metric. It is used to continue the exploration of the…
Mass inflation inside non-Abelian black holes
Peter Breitenlohner, George Lavrelashvili, Dieter Maison
The interior geometry of static, spherically symmetric black holes of the Einstein-Yang-Mills-Higgs theory is analyzed. It is found that in contrast to the Abelian case generically…
The Matter Plus Black Hole Problem in Axisymmetry
S. R. Brandt, J. A. Font
We present preliminary results in our long-term project of studying the evolution of matter in a dynamical spacetime. To achieve this, we have developed a new code to evolve axisym…
BH Punctures as Initial Data for General Relativity
S. R. Brandt, B. Bruegmann
We construct initial data for several black holes with arbitrary momenta and spins by a new method that is based on a compactification of Brill-Lindquist wormholes. When treated nu…
Form Factors, Thermal States and Modular Structures
M. R. Niedermaier
Form factor sequences of an integrable QFT can be defined axiomatically as solutions of a system of recursive functional equations, known as ``form factor equations''. We show that…
Physical Properties of Quantum Field Theory Measures
J. M. Mourao, T. Thiemann, J. M. Velhinho
Well known methods of measure theory on infinite dimensional spaces are used to study physical properties of measures relevant to quantum field theory. The difference of typical co…
Three Dimensional Distorted Black Holes: Initial Data and Evolution
S. R. Brandt, K. Camarda, E. Seidel
We present a new class of 3D black hole initial data sets for numerical relativity. These data sets go beyond the axisymmetric, ``gravity wave plus rotating black hole'' single bla…
Yangian Symmetry in Integrable Quantum Gravity
D. Korotkin, H. Samtleben
Dimensional reduction of various gravity and supergravity models leads to effectively two-dimensional field theories described by gravity coupled G/H coset space sigma-models. The…
Detecting a stochastic background of gravitational radiation: Signal processing strategies and sensitivities
Bruce Allen, Joseph D. Romano
We analyze the signal processing required for the optimal detection of a stochastic background of gravitational radiation using laser interferometric detectors. Starting with basic…
Quantum Inhomogeneities in String Cosmology
A. Buonanno, K. Meissner, C. Ungarelli +1
Within two specific string cosmology scenarios --differing in the way the pre- and post-big bang phases are joined-- we compute the size and spectral slope of various types of cosm…
Effective Chiral Meson-Baryon Lagrangian from Path Integral Hadronization of a Quark-Diquark Model
Dietmar Ebert, Thomas Jurke
The approach of path integral hadronization, applied to a quark-diquark toy model, is used to derive an effective chiral meson-baryon Lagrangian. In this approach the Goldberger-Tr…
Introduction to the Analysis of Low-Frequency Gravitational Wave Data
B. F. Schutz
The space-based gravitational wave detector LISA will observe in the low-frequency gravitational-wave band (0.1 mHz up to 1 Hz). LISA will search for a variety of expected signals,…
Low-Frequency Sources of Gravitational Waves: A Tutorial
B. F. Schutz
Gravitational wave detectors in space, particularly the LISA project, can study a rich variety of astronomical systems whose gravitational radiation is not detectable from the grou…
Cosmological spacetimes not covered by a constant mean curvature slicing
James Isenberg, Alan D. Rendall
We show that there exist maximal globally hyperbolic solutions of the Einstein-dust equations which admit a constant mean curvature Cauchy surface, but are not covered by a constan…
On the consistency of the constraint algebra in spin network quantum gravity
Rodolfo Gambini, Jerzy Lewandowski, Donald Marolf +1
We point out several features of the quantum Hamiltonian constraints recently introduced by Thiemann for Euclidean gravity. In particular we discuss the issue of the constraint alg…
Loop constraints: A habitat and their algebra
Jerzy Lewandowski, Donald Marolf
This work introduces a new space $\T'_*$ of `vertex-smooth' states for use in the loop approach to quantum gravity. Such states provide a natural domain for Euclidean Hamiltonian c…
Stuffed Black Holes
A. Arbona, C. Bona, J. Carot +3
Initial data corresponding to spacetimes containing black holes are considered in the time symmetric case. The solutions are obtained by matching across the apparent horizon differ…

Stephan Melosch, Hermann Nicolai
A set of new canonical variables for supergravity is proposed which renders the supersymmetry variations and the supersymmetry constraint polynomial. The construction is bas…
