MERA as a holographic strange correlator
Nathan A. McMahon, Sukhbinder Singh, Gavin K. Brennen
The multi-scale entanglement renormalization ansatz (MERA) is a tensor network that can efficiently parameterize critical ground states on a 1D lattice, and also suggestively imple…
Constraints for Three-Dimensional Higher-Spin Interactions and Conformal Correlators
Stefan Fredenhagen, Olaf Krüger, Karapet Mkrtchyan
In the context of higher-spin holography, we compare the classification of cubic interaction vertices for higher-spin gravity theories in three dimensions to the possible three-poi…
A first search for a stochastic gravitational-wave background from ultralight bosons
Leo Tsukada, Thomas Callister, Andrew Matas +1
In this work, we develop a Bayesian data analysis framework to study the SGWB from bosonic clouds using data from Advanced LIGO and Advanced Virgo, building on previous work by Bri…
Surrogate model for an aligned-spin effective one body waveform model of binary neutron star inspirals using Gaussian process regression
Benjamin D. Lackey, Michael Pürrer, Andrea Taracchini +1
Fast and accurate waveform models are necessary for measuring the properties of inspiraling binary neutron star systems such as GW170817. We present a frequency-domain surrogate ve…
Non-commutative Fourier transform for the Lorentz group via the Duflo map
Daniele Oriti, Giacomo Rosati
We defined a non-commutative algebra representation for quantum systems whose phase space is the cotangent bundle of the Lorentz group, and the non-commutative Fourier transform en…
Entanglement renormalization and symmetry fractionalization
Sukhbinder Singh, Nathan McMahon, Gavin Brennen
It is well known that the matrix product state (MPS) description of a gapped ground state with a global on-site symmetry can exhibit "symmetry fractionalization". Namely, even thou…
Asymptotic structure of a massless scalar field and its dual two-form field at spatial infinity
Marc Henneaux, Cedric Troessaert
Relativistic field theories with a power law decay in at spatial infinity generically possess an infinite number of conserved quantities because of Lorentz invariance. Mos…
Gravitational waveforms from SpEC simulations : neutron star-neutron star and low-mass black hole-neutron star binaries
Francois Foucart, Matthew D. Duez, Tanja Hinderer +9
Gravitational waveforms from numerical simulations are a critical tool to test and analytically calibrate the waveform models used to study the properties of merging compact object…
Instantons on hyperkähler manifolds
Chandrashekar Devchand, Massimiliano Pontecorvo, Andrea Spiro
An instanton on a (pseudo-)hyperkähler manifold is a vector bundle associated to a principal -bundle with a connection whose curvature is pointwise invarian…
LISA Pathfinder Platform Stability and Drag-free Performance
Michele Armano, Heather Audley, Jonathon Baird +75
The science operations of the LISA Pathfinder mission has demonstrated the feasibility of sub-femto-g free-fall of macroscopic test masses necessary to build a LISA-like gravitatio…
Listening to the gravitational wave sound of circumbinary exoplanets
Nicola Tamanini, Camilla Danielski
To date more than 3500 exoplanets have been discovered orbiting a large variety of stars. Due to the sensitivity limits of the currently used detection techniques, these planets po…
New dual gravitational charges
Hadi Godazgar, Mahdi Godazgar, C. N. Pope
We show that there are a further infinite number of, previously unknown, supertranslation charges. These can be viewed as duals of the known BMS charges corresponding to supertrans…
Searches for Continuous Gravitational Waves from Fifteen Supernova Remnants and Fomalhaut b with Advanced LIGO
The LIGO Scientific Collaboration, the Virgo Collaboration, B. P. Abbott +1129
We describe directed searches for continuous gravitational waves from sixteen well localized candidate neutron stars assuming none of the stars has a binary companion. The searches…
Towards the n-point one-loop superstring amplitude III: One-loop correlators and their double-copy structure
Carlos R. Mafra, Oliver Schlotterer
In this final part of a series of three papers, we will assemble supersymmetric expressions for one-loop correlators in pure-spinor superspace that are BRST invariant, local, and s…

Carlos R. Mafra, Oliver Schlotterer
This is the second installment of a series of three papers in which we describe a method to determine higher-point correlation functions in one-loop open-superstring amplitudes fro…

Carlos R. Mafra, Oliver Schlotterer
This is the first installment of a series of three papers in which we describe a method to determine higher-point correlation functions in one-loop open-superstring amplitudes from…
Entanglement and chaos in warped conformal field theories
Luis Apolo, Song He, Wei Song +2
Various aspects of warped conformal field theories (WCFTs) are studied including entanglement entropy on excited states, the Renyi entropy after a local quench, and out-of-time-ord…
Algebraic Structures in the Coupling of Gravity to Gauge Theories
David Prinz
This article is an extension of the author's second master thesis [1]. It aims to introduce to the theory of perturbatively quantized General Relativity coupled to Spinor Electrody…
Surrogate model of hybridized numerical relativity binary black hole waveforms
Vijay Varma, Scott E. Field, Mark A. Scheel +3
Numerical relativity (NR) simulations provide the most accurate binary black hole gravitational waveforms, but are prohibitively expensive for applications such as parameter estima…
Tower of subleading dual BMS charges
Hadi Godazgar, Mahdi Godazgar, C. N. Pope
We supplement the recently found dual gravitational charges with dual charges for the whole BMS symmetry algebra. Furthermore, we extend the dual charges away from null infinity, d…
Scattering of Spinning Black Holes from Exponentiated Soft Factors
Alfredo Guevara, Alexander Ochirov, Justin Vines
We provide evidence that the classical scattering of two spinning black holes is controlled by the soft expansion of exchanged gravitons. We show how an exponentiation of Cachazo-S…
