Gravitational corrections to the Euler-Heisenberg Lagrangian
Fiorenzo Bastianelli, Jose Manuel Davila, Christian Schubert
We use the worldline formalism for calculating the one-loop effective action for the Einstein-Maxwell background induced by charged scalars or spinors, in the limit of low energy a…
Motion of test bodies in theories with nonminimal coupling
Dirk Puetzfeld, Yuri N. Obukhov
We derive the equations of motion of test bodies for a theory with nonminimal coupling by means of a multipole method. The propagation equations for pole-dipole particles are worke…
Experimental test of nonclassicality criteria
T. Kiesel, W. Vogel, B. Hage +3
We experimentally examine the nonclassical character of a class of non-Gaussian states known as phase-diffused squeezed states. These states may show no squeezing effect at all, an…
A universal inequality for axisymmetric and stationary black holes with surrounding matter in the Einstein-Maxwell theory
Jörg Hennig, Carla Cederbaum, Marcus Ansorg
We prove that in Einstein-Maxwell theory the inequality holds for any sub-extremal axisymmetric and stationary black hole with arbitrary surrounding matte…
Modelling the final state from binary black-hole coalescences
Luciano Rezzolla
Over the last few years enormous progress has been made in the numerical description of the inspiral and merger of binary black holes. A particular effort has gone into the modelli…
Piecewise linear loop quantum gravity
Jonathan Engle
We define a modification of LQG in which graphs are required to consist in piecewise linear edges, which we call piecewise linear LQG (plLQG). At the diffeomorphism invariant level…
Preparation of distilled and purified continuous variable entangled states
Boris Hage, Aiko Samblowski, James DiGuglielmo +3
The distribution of entangled states of light over long distances is a major challenge in the field of quantum information. Optical losses, phase diffusion and mixing with thermal…
An improved formulation of the relativistic hydrodynamics equations in 2D Cartesian coordinates
Thorsten Kellermann, Luca Baiotti, Bruno Giacomazzo +1
A number of astrophysical scenarios possess and preserve an overall cylindrical symmetry also when undergoing a catastrophic and nonlinear evolution. Exploiting such a symmetry, th…
Finite Volume Spectrum of 2D Field Theories from Hirota Dynamics
Nikolay Gromov, Vladimir Kazakov, Pedro Vieira
We propose, using the example of the O(4) sigma model, a general method for solving integrable two dimensional relativistic sigma models in a finite size periodic box. Our starting…
Infinite-Dimensional Representations of 2-Groups
John C. Baez, Aristide Baratin, Laurent Freidel +1
A "2-group" is a category equipped with a multiplication satisfying laws like those of a group. Just as groups have representations on vector spaces, 2-groups have representations…
Degeneracies in Sky Localisation Determination from a Spinning Coalescing Binary through Gravitational Wave Observations: a Markov-Chain Monte-Carlo Analysis for two Detectors
V. Raymond, M. V. van der Sluys, I. Mandel +3
Gravitational-wave signals from inspirals of binary compact objects (black holes and neutron stars) are primary targets of the ongoing searches by ground-based gravitational-wave i…
The Holst Spin Foam Model via Cubulations
Aristide Baratin, Cecilia Flori, Thomas Thiemann
Spin foam models are an attempt for a covariant, or path integral formulation of canonical loop quantum gravity. The construction of such models usually rely on the Plebanski formu…
Finite Difference Methods for Second Order in Space, First Order in Time Hyperbolic Systems and the Linear Shifted Wave Equation as a Model Problem in Numerical Relativity
M. Chirvasa, S. Husa
Motivated by the problem of solving the Einstein equations, we discuss high order finite difference discretizations of first order in time, second order in space hyperbolic systems…
Scattering in Mass-Deformed N>=4 Chern-Simons Models
Abhishek Agarwal, Niklas Beisert, Tristan McLoughlin
We investigate the scattering matrix in mass-deformed N>=4 Chern-Simons models including as special cases the BLG and ABJM theories of multiple M2 branes. Curiously the structure o…
On the Solution Space of Differentially Rotating Neutron Stars in General Relativity
Marcus Ansorg, Dorota Gondek-Rosińska, Loïc Villain
A highly accurate, multi-domain spectral code is used in order to construct sequences of general relativistic, differentially rotating neutron stars in axisymmetry and stationarity…
DC-readout of a signal-recycled gravitational wave detector
S. Hild, H. Grote, J. Degallaix +10
All first-generation large-scale gravitational wave detectors are operated at the dark fringe and use a heterodyne readout employing radio frequency (RF) modulation-demodulation te…
Rotating elastic bodies in Einstein gravity
Lars Andersson, Robert Beig, Bernd Schmidt
We prove that, given a stress-free, axially symmetric elastic body, there exists, for sufficiently small values of the gravitational constant and of the angular frequency, a unique…
Probing nonstandard interactions with reactor neutrinos
J. Barranco, O. G. Miranda, T. I. Rashba
New limits on the weak mixing angle and on the electron neutrino effective charge radius in the low energy regime, below 100 MeV, are obtained from a combined fit of all electron-(…
The time evolution of marginally trapped surfaces
Lars Andersson, Marc Mars, Jan Metzger +1
In previous work we have shown the existence of a dynamical horizon or marginally trapped tube (MOTT) containing a given strictly stable marginally outer trapped surface (MOTS). In…
Universality of global dynamics for the cubic wave equation
Piotr Bizon, Anil Zenginoglu
We consider the initial value problem for the spherically symmetric, focusing cubic wave equation in three spatial dimensions. We give numerical and analytical evidence for the exi…
Quantum Symmetries and Marginal Deformations
Teresia Mansson, Konstantinos Zoubos
We study the symmetries of the N=1 exactly marginal deformations of N=4 Super Yang-Mills theory. For generic values of the parameters, these deformations are known to break the SU(…
Towards a gauge-polyvalent Numerical Relativity code
Daniela Alic, Carles Bona, Carles Bona-Casas
The gauge polyvalence of a new numerical code is tested, both in harmonic-coordinate simulations (gauge-waves testbed) and in singularity-avoiding coordinates (simple Black-Hole si…
Massive Black Hole Binary Inspirals: Results from the LISA Parameter Estimation Taskforce
K. G. Arun, Stas Babak, Emanuele Berti +14
The LISA Parameter Estimation (LISAPE) Taskforce was formed in September 2007 to provide the LISA Project with vetted codes, source distribution models, and results related to para…
Scalar heat kernel with boundary in the worldline formalism
Fiorenzo Bastianelli, Olindo Corradini, Pablo A. G. Pisani +1
The worldline formalism has in recent years emerged as a powerful tool for the computation of effective actions and heat kernels. However, implementing nontrivial boundary conditio…
