A Covariant Formulation of Logarithmic Supertranslations at Spatial Infinity
Florian Girelli, Simon Langenscheidt, Giulio Neri +2
We investigate the asymptotic symmetries of asymptotically flat spacetimes at spatial infinity. We propose a new symplectic structure and conservative boundary conditions in a poly…
On Gauge-Invariant Entire-Function Regulators and UV Finiteness in NonLocal Quantum Field Theory
J. W. Moffat, E. J. Thompson
In this paper we clarify the status of gauge invariant entire function regulators in NonLocal Quantum Field Theory, in this the regulator is implemented as an entire function of th…
Ultraviolet Completion of the Big Bang in Quadratic Gravity
Ruolin Liu, Jerome Quintin, Niayesh Afshordi
We present a quantum quadratic gravity inflationary scenario that can accommodate the new cosmological constraints, which have disfavored Starobinsky inflation. The theory is asymp…
(Un)solvable Matrix Models for BPS Correlators
Prokopii Anempodistov, Adolfo Holguin, Vladimir Kazakov +1
We propose and study a family of complex matrix models computing the protected two- and three-point correlation functions in SYM. Our description allows us to direc…
Quiver superconformal index and giant gravitons: asymptotics and expansions
Souradeep Purkayastha, Zishen Qu, Ali Zahabi
We study asymptotics of the , superconformal index for toric quiver gauge theories. Using graph-theoretic and algebraic factorization techniques, we obtain a c…
Free and Interacting Fermionic Conformal Field Theories on the Fuzzy Sphere
Zheng Zhou, Davide Gaiotto, Yin-Chen He
The fuzzy-sphere regularisation is a powerful tool to study conformal field theories (CFT) in three spacetime dimensions. In this paper, we extend its scope to CFTs with local ferm…
Non-Perturbative -matrix Renormalization
Laurent Freidel, José Padua-Argüelles, Susanne Schander +1
We propose a renormalization group flow equation for a functional that generates -matrix elements and which captures similarities to the well-known Wetterich and Polchinski equa…
Beyond Noether: A Covariant Study of Poisson-Lie Symmetries in Low Dimensional Field Theory
Florian Girelli, Christopher Pollack, Aldo Riello
We explore global Poisson-Lie (PL) symmetries using a Lagrangian, or "covariant phase space" approach, that manifestly preserves spacetime covariance. PL symmetries are the classic…
Asymptotic Higher Spin Symmetries IV: Einstein-Yang-Mills Theory
Nicolas Cresto, Laurent Freidel
We generalize the analysis of the asymptotic higher spin symmetries developed in the first three parts of this series by considering the minimal coupling of Einstein Gravity and Ya…
Cuscuton Bounce Beyond the Linear Regime: Bispectrum and Strong Coupling Constraints
Amir Dehghani, Ghazal Geshnizjani, Jerome Quintin
Cuscuton Gravity is characterized as a scalar field that can be added to general relativity without introducing any new dynamical degrees of freedom on a cosmological background. Y…
Asymptotic Higher Spin Symmetries III: Noether Realization in Yang-Mills Theory
Nicolas Cresto
We construct a non-perturbative action of the higher spin symmetry algebra on the asymptotic Yang-Mills phase space. We introduce a symmetry algebroid which admits a realization on…
Celestial Quantum Error Correction II: From Qudits to Celestial CFT
Alfredo Guevara, Yangrui Hu
A holographic CFT description of asymptotically flat spacetimes inherits vacuum degeneracies and IR divergences from its gravitational dual. We devise a Quantum Error Correcting (Q…
Smart Holes: Analogue black holes with the right temperature and entropy
Jiayue Yang, Niayesh Afshordi, Mahdi Torabian +2
In analogue gravity studies, the goal is to replicate black hole phenomena, such as Hawking radiation, within controlled laboratory settings. In the realm of condensed matter syste…
Conformal Cores of Quantum Black Holes in Quadratic Gravity
Ruolin Liu, Jerome Quintin, Niayesh Afshordi
We explore the possibility that quadratic gravity, as a renormalizable theory, describes the interior of quantum black holes. We find new exact power-law solutions to pure quadrati…

Di Wu, Wentao Liu, Shuang-Qing Wu +1
By viewing black hole solutions as topological defects in thermodynamic parameter space, we unveil a novel topological class and two new topological subclasses, respectively denote…
Asymptotic Higher Spin Symmetries II: Noether Realization in Gravity
Nicolas Cresto, Laurent Freidel
In this paper we construct a non-perturbative action of the higher spin symmetry algebra on the gravitational phase space. We introduce a symmetry algebroid which all…
A new series of 3D CFTs with global symmetry on fuzzy sphere
Zheng Zhou, Yin-Chen He
The quest to discover new 3D CFTs has been intriguing for physicists. For this purpose, fuzzy sphere reguarlisation that studies interacting quantum systems defined on the lowest L…
Asymptotic Higher Spin Symmetries I: Covariant Wedge Algebra in Gravity
Nicolas Cresto, Laurent Freidel
In this paper, we study gravitational symmetry algebras that live on 2-dimensional cuts of asymptotic infinity. We define a notion of wedge algebra which depen…
Studying the 3d Ising surface CFTs on the fuzzy sphere
Zheng Zhou, Yijian Zou
Boundaries not only are fundamental elements in nearly all realistic physical systems, but also greatly enrich the structure of quantum field theories. In this paper, we demonstrat…
Higher Gauge Theory and Integrability
Hank Chen, Joaquin Liniado
In recent years, significant progress has been made in the study of integrable systems from a gauge theoretic perspective. This development originated with the introduction of d…
Holographic scattering and non-minimal RT surfaces
Jacqueline Caminiti, Batia Friedman-Shaw, Alex May +2
In the AdS/CFT correspondence, the causal structure of the bulk AdS spacetime is tied to entanglement in the dual CFT. This relationship is captured by the connected wedge theorem,…
From area metric backgrounds to the cosmological constant and corrections to the Polyakov action
Johanna Borissova, Pei-Ming Ho
Area metrics and area metric backgrounds provide a unified framework for quantum gravity. They encode physical degrees of freedom beyond those of a metric. These non-metric degrees…
