Loop Quantum Cosmology and Boundary Proposals
Martin Bojowald, Kevin Vandersloot
For many years, the most active area of quantum cosmology has been the issue of choosing boundary conditions for the wave function of a universe. Recently, loop quantum cosmology,…
Classical and Quantum Branes in c=1 String Theory and Quantum Hall Effect
Alexey Boyarsky, Bogdan Kulik, Oleg Ruchayskiy
Interpretation of D1 and D0-branes in 1+1 string theory as classical and quantum eigen-values in dual c=1 Matrix Quantum Mechanics (MQM) was recently suggested. MQM is known to be…
De Sitter vacua from N=2 gauged supergravity
Klaus Behrndt, Swapna Mahapatra
Typical de Sitter (dS) vacua of gauged supergravity correspond to saddle points of the potential and often the unstable mode runs into a singularity. We explore the possibility to…
Analysis of First LIGO Science Data for Stochastic Gravitational Waves
LIGO Scientific Collaboration, B. Abbott
We present the analysis of between 50 and 100 hrs of coincident interferometric strain data used to search for and establish an upper limit on a stochastic background of gravitatio…
Effective mass of a radiating charged particle in Einstein's universe
Elias C. Vagenas
The effective gravitational mass as well as the energy and momentum distributions of a radiating charged particle in Einstein's universe are evaluated. The Moller's energy-momentum…
Multi-spin strings on AdS(5)xT(1,1) and operators of N=1 superconformal theory
Nakwoo Kim
We study rotating strings with multiple spins in the background of , which is dual to a superconformal field theory with global symmetry $SU(2)…
Asymptotics of solutions of the Einstein equations with positive cosmological constant
Alan D. Rendall
A positive cosmological constant simplifies the asymptotics of forever expanding cosmological solutions of the Einstein equations. In this paper a general mathematical analysis on…
Bulk Witten Indices from D=10 Yang Mills Integrals
Thomas Fischbacher
Values for the bulk Witten indices for D=10 Yang-Mills integrals for some regular simple groups of rank 4 and 5 are calculated by employing the BRST deformation technique by Moore,…
Symmetry breaking, permutation D-branes on group manifolds: boundary states and geometric description
Gor Sarkissian, Marija Zamaklar
We use the permutation symmetry between the product of several group manifolds in combination with orbifolds and T-duality to construct new classes of symmetry breaking branes on p…
Chronological structure of a Goedel type universe with negative cosmological constant
Klaus Behrndt, Markus Pössel
We show that the Goedel solution of five-dimensional gauged supergravity contains either closed time-like curves through every space-time point or none at all, dependent on the rot…
First upper limits from LIGO on gravitational wave bursts
LIGO Scientific Collaboration, B. Abbott
We report on a search for gravitational wave bursts using data from the first science run of the LIGO detectors. Our search focuses on bursts with durations ranging from 4 ms to 10…
Horizons and plane waves: A review
Veronika E. Hubeny, Mukund Rangamani
We review the attempts to construct black hole/string solutions in asymptotically plane wave spacetimes. First, we demonstrate that geometries admitting a covariantly constant null…
Constraints Algebra and Equations of Motion in Bohmian Interpretation of Quantum Gravity
Ali Shojai, Fatimah Shojai
It is shown that introducing the quantum effects using deBroglie--Bohm theory in the canonical formulation of gravity would change the constraints algebra. The new algebra is deriv…
Twistors, CFT and Holography
Kirill Krasnov
According to one of many equivalent definitions of twistors a (null) twistor is a null geodesic in Minkowski spacetime. Null geodesics can intersect at points (events). The idea of…
Anti-de-Sitter vacua require fermionic brane charges
Kasper Peeters, Marija Zamaklar
We argue that a modification of the super-AdS algebras which accounts for the presence of D-branes requires not only the inclusion of bosonic brane charges, but also the inclusion…
On the Integrability of large N Plane-Wave Matrix Theory
Thomas Klose, Jan Plefka
We show the three-loop integrability of large N plane-wave matrix theory in a subsector of states comprised of two complex light scalar fields. This is done by diagonalizing the th…
Upper limits on the strength of periodic gravitational waves from PSR J1939+2134
B. Allen, G. Woan
The first science run of the LIGO and GEO gravitational wave detectors presented the opportunity to test methods of searching for gravitational waves from known pulsars. Here we pr…
Higher order loop equations for A_r and D_r quiver matrix models
Stefano Chiantese, Albrecht Klemm, Ingo Runkel
We use free boson techniques to investigate A-D-E-quiver matrix models. Certain higher spin fields in the free boson formulation give rise to higher order loop equations valid at f…
Fluxes in M-theory on 7-manifolds: G-structures and Superpotential
Klaus Behrndt, Claus Jeschek
We consider compactifications of M-theory on 7-manifolds in the presence of 4-form fluxes, which leave at least four supercharges unbroken. We focus especially on the case, where t…
Spinning strings in AdS_5 x S^5: new integrable system relations
G. Arutyunov, J. Russo, A. A. Tseytlin
A general class of rotating closed string solutions in AdS_5 x S^5 is shown to be described by a Neumann-Rosochatius one-dimensional integrable system. The latter represents an osc…
Homogeneous Loop Quantum Cosmology: The Role of the Spin Connection
Martin Bojowald, Ghanashyam Date, Kevin Vandersloot
Homogeneous cosmological models with non-vanishing intrinsic curvature require a special treatment when they are quantized with loop quantum cosmological methods. Guidance from the…
Quantum suppression of the generic chaotic behavior close to cosmological singularities
Martin Bojowald, Ghanashyam Date
In classical general relativity, the generic approach to the initial singularity is very complicated as exemplified by the chaos of the Bianchi IX model which displays the generic…
On the spectrum of AdS/CFT beyond supergravity
N. Beisert, M. Bianchi, J. F. Morales +1
We test the spectrum of string theory on AdS_5 x S^5 derived in hep-th/0305052 against that of single-trace gauge invariant operators in free N=4 super Yang-Mills theory. Masses of…
Matching Higher Conserved Charges for Strings and Spins
G. Arutyunov, M. Staudacher
We demonstrate that the recently found agreement between one-loop scaling dimensions of large dimension operators in N=4 gauge theory and energies of spinning strings on AdS_5 x S^…
