Duality in Gauge Theory, Gravity and String Theory
Uri Kol, Shing-Tung Yau
Einstein's theory in the vacuum was recently shown to possess an duality invariance, which is broken by coupling to matter. Duality invariance can be restored by enlarging…
Duality in Einstein's Gravity
Uri Kol
We show that the Einstein equations in the vacuum are invariant under an duality symmetry which rotates the curvature 2-form into its tangent space Hodge dual. Akin to elec…
Supertranslation-Invariant Dressed Lorentz Charges
Reza Javadinezhad, Uri Kol, Massimo Porrati
We present an explicit formula for Lorentz boosts and rotations that commute with BMS supertranslations in asymptotically flat spacetimes. Key to the construction is the use of inf…
The Radial Action from Probe Amplitudes to All Orders
Uri Kol, Donal O'connell, Ofri Telem
We extract the relativistic classical radial action from scattering amplitudes, to all orders in perturbation theory, in the probe limit. Our sources include point charges and mono…
Classical double copy at null infinity
Tim Adamo, Uri Kol
We give two double copy prescriptions which construct asymptotically flat solutions in gravity from asymptotically flat gauge fields. The first prescription applies to radiative fi…
Subleading BMS Charges and The Lorentz Group
Uri Kol
The extended BMS group includes supertranslation, dual supertranslation and Lorentz transformations. The generators of these symmetries can be classified according to their parity…
Amplitudes from Coulomb to Kerr-Taub-NUT
William T. Emond, Yu-tin Huang, Uri Kol +2
Electric-magnetic duality, the Newman-Janis shift, and the double copy all act by elementary operations on three-point amplitudes. At the same time, they generate a network of inte…
Dual Komar Mass, Torsion and Riemann-Cartan Manifolds
Uri Kol
The dual Komar mass generalizes the concept of the NUT parameter and is akin to the magnetic charge in electrodynamics. In asymptotically flat spacetimes it coincides with the dual…
Gravitational Wu-Yang Monopoles
Uri Kol, Massimo Porrati
We show that in an asymptotically flat space where an S-Matrix can be defined, dual supertranslations leave all its matrix elements invariant and the Hilbert space of asymptotic st…
The Double Copy of Electric-Magnetic Duality
Yu-tin Huang, Uri Kol, Donal O'Connell
We argue that the complex transformation relating the Schwarzschild to the Taub-NUT metric, introduced by Talbot, is in fact an electric-magnetic duality transformation. We show th…
Properties of Dual Supertranslation Charges in Asymptotically Flat Spacetimes
Uri Kol, Massimo Porrati
We study several properties of some new charges of asymptotically flat spacetimes. These dual supertranslation charges are akin to the magnetic large charges in QED. In this…
Comments on Lorentz Transformations, Dressed Asymptotic States and Hawking Radiation
Reza Javadinezhad, Uri Kol, Massimo Porrati
We consider two applications of the factorization of infrared dynamics in QED and gravity. The first is a redefinition of the Lorentz transformations that makes them commute with s…
Entropy functional and the holographic attractor mechanism
Alejandro Cabo-Bizet, Uri Kol, Leopoldo A. Pando Zayas +2
We provide a field theory interpretation of the attractor mechanism for asymptotically AdS dyonic BPS black holes whose entropy is captured by the supersymmetric index of the t…
Asymptotic Dynamics in Perturbative Quantum Gravity and BMS Supertranslations
Sangmin Choi, Uri Kol, Ratindranath Akhoury
Recently it has been shown that infrared divergences in the conventional S-matrix elements of gauge and gravitational theories arise from a violation of the conservation laws assoc…
Holography for on and Supergravity
Uri Kol
We study the sector of the mass deformation of super Yang-Mills on . The gravity dual of this sector is supergravity…
Holography for on
Nikolay Bobev, Henriette Elvang, Uri Kol +2
We construct the five-dimensional supergravity dual of the mass deformation of the supersymmetric Yang-Mills theory on and use it to calcul…
Confinement, Phase Transitions and non-Locality in the Entanglement Entropy
Uri Kol, Carlos Nunez, Daniel Schofield +2
In this paper we study the conjectural relation between confinement in a quantum field theory and the presence of a phase transition in its corresponding entanglement entropy. We d…
On the dual flow of slow-roll Inflation
Uri Kol
We study the dual 3d Euclidean RG flow of single-field slow-roll Inflation using the postulates of the dS/CFT correspondence. For that purpose we solve for the inflationary fluctua…
The holographic dilaton
Carlos Hoyos, Uri Kol, Jacob Sonnenschein +1
We study a set of examples of holographic duals to theories with spontaneous breaking of conformal invariance in different dimensions. The geometries are domain walls interpolating…
The a-theorem and conformal symmetry breaking in holographic RG flows
Carlos Hoyos, Uri Kol, Jacob Sonnenschein +1
We study holographic models describing an RG flow between two fixed points driven by a relevant scalar operator. We show how to introduce a spurion field to restore Weyl invariance…
Can holography reproduce the QCD Wilson line?
Uri Kol, Jacob Sonnenschein
Recently a remarkable agreement was found between lattice simulations of long Wilson lines and behavior of the Nambu Goto string in flat space-time. However, the latter fails to fi…
