Rough solutions of Einstein vacuum equations in CMCSH gauge
Qian Wang
In this paper, we consider very rough solutions to Cauchy problem for the Einstein vacuum equations in CMC spacial harmonic gauge, and obtain the local well-posedness result in $H^…
The 10m AEI prototype facility A brief overview
Tobias Westphal, Gerald Bergmann, Alessandro Bertolini +24
The AEI 10 m prototype interferometer facility is currently being constructed at the Albert Einstein Institute in Hannover, Germany. It aims to perform experiments for future gravi…
Where is the electrostatic self-energy localized in general relativity?
Carlos Barcelo, Jose Luis Jaramillo
We discuss an alternative way of prescribing the spacetime geometry associated with a non-radiating distribution of charged matter. It is based on the possibility that the electros…
Spontaneous symmetry breaking and gravity
Kirill Krasnov
Gravity is usually considered to be irrelevant as far as the physics of elementary particles is concerned and, in particular, in the context of the spontaneous symmetry breaking (S…
Local tuning of Coupling Constants allows for Quantum Fields in Curved Spacetime in the Lab
Isabeau Prémont-Schwarz
In this paper we will investigate how one can create emergent curved spacetimes by locally tuning the coupling constants of condensed matter systems. In the continuum limit we thus…
Cycles in the Multiverse
Matthew C. Johnson, Jean-Luc Lehners
Eternal inflation is a seemingly generic consequence of theories that give rise to accelerated expansion of the universe and possess multiple vacuum states. Making predictions in a…
Ten questions on Group Field Theory (and their tentative answers)
Aristide Baratin, Daniele Oriti
We provide a short and non-technical summary of our current knowledge and some possible perspectives on the group field theory formalism for quantum gravity, in the form of a (part…
Quantum back-reaction in a universe with positive cosmological constant
David Brizuela
Semiclassical techniques have proven to be a very powerful method to extract physical effects from different quantum theories. Therefore, it is expected that in the near future the…
Group Fourier transform and the phase space path integral for finite dimensional Lie groups
Matti Raasakka
We formulate a notion of group Fourier transform for a finite dimensional Lie group. The transform provides a unitary map from square integrable functions on the group to square in…
Experimenting with Quantum Fields in Curved Spacetime in the Lab
Isabeau Prémont-Schwarz
In this paper we will investigate how one can create emergent curved spacetimes by locally tuning the coupling constants of condensed matter systems. In the continuum limit we thus…
Non-commutative holonomies in 2+1 LQG and Kauffman's brackets
Karim Noui, Alejandro Perez, Daniele Pranzetti
We investigate the canonical quantization of 2+1 gravity with Λ > 0 in the canonical framework of LQG. A natural regularization of the constraints of 2+1 gravity can be defined in…
Characterization of thermal effects in the Enhanced LIGO Input Optics
K. L. Dooley, M. A. Arain, D. Feldbaum +14
We present the design and performance of the LIGO Input Optics subsystem as implemented for the sixth science run of the LIGO interferometers. The Initial LIGO Input Optics experie…
Resolving multiple supermassive black hole binaries with pulsar timing arrays
Stanislav Babak, Alberto Sesana
We study the capability of a pulsar timing array (PTA) to individually resolve and localize in the sky monochromatic gravitational wave (GW) sources. Given a cosmological populatio…
Generic effective source for scalar self-force calculations
Barry Wardell, Ian Vega, Jonathan Thornburg +1
A leading approach to the modelling of extreme mass ratio inspirals involves the treatment of the smaller mass as a point particle and the computation of a regularized self-force a…
Quantum Signatures of the Optomechanical Instability
Jiang Qian, A. A. Clerk, K. Hammerer +1
In the past few years, coupling strengths between light and mechanical motion in optomechanical setups have improved by orders of magnitude. Here we show that, in the standard setu…
Consistent truncation of d = 11 supergravity on AdS_4 x S^7
Hermann Nicolai, Krzysztof Pilch
We study the system of equations derived twenty five years ago by B. de Wit and the first author [Nucl. Phys. B281 (1987) 211] as conditions for the consistent truncation of eleven…
Upper limits on a stochastic gravitational-wave background using LIGO and Virgo interferometers at 600-1000 Hz
J. Abadie, B. P. Abbott, R. Abbott +782
A stochastic background of gravitational waves is expected to arise from a superposition of many incoherent sources of gravitational waves, of either cosmological or astrophysical…
Self-consistent orbital evolution of a particle around a Schwarzschild black hole
Peter Diener, Ian Vega, Barry Wardell +1
The motion of a charged particle is influenced by the self-force arising from the particle's interaction with its own field. In a curved spacetime, this self-force depends on the e…
Singular topologies in the Boulatov model
Sylvain Carrozza
Through the question of singular topologies in the Boulatov model, we illustrate and summarize some of the recent advances in Group Field Theory.
Supertranslations and Holographic Stress Tensor
Amitabh Virmani
It is well known in the context of four dimensional asymptotically flat spacetimes that the leading order boundary metric must be conformal to unit de Sitter metric when hyperbolic…
Multimessenger Science Reach and Analysis Method for Common Sources of Gravitational Waves and High-energy Neutrinos
Bruny Baret, Imre Bartos, Boutayeb Bouhou +23
We present the baseline multimessenger analysis method for the joint observations of gravitational waves (GW) and high-energy neutrinos (HEN), together with a detailed analysis of…
Jumpstarting the all-loop S-matrix of planar N=4 super Yang-Mills
Simon Caron-Huot, Song He
We derive a set of first-order differential equations obeyed by the S-matrix of planar maximally supersymmetric Yang-Mills theory. The equations, based on the Yangian symmetry of t…
Tailoring diffusion in analogue spacetimes
Matteo Smerlak
Diffusive transport is characterized by the scaling law . In this letter we show that this relationship is significantly altered in curved analogue space…
Strong Einstein-Podolsky-Rosen steering with unconditional entangled states
Sebastian Steinlechner, Jöran Bauchrowitz, Tobias Eberle +1
In 1935 Schrödinger introduced the terms entanglement and steering in the context of the famous gedanken experiment discussed by Einstein, Podolsky, and Rosen (EPR). Here, we repor…
