On the Sugawara Current Algebra Proposal for M-Theory
Keith Glennon
We examine the proposal of [29] that M-theory may admit a Sugawara-type current algebra formulation based on . Motivated by the role of generalized coordinate…
BV-BRST Noether theorem
Glenn Barnich, Laurent Baulieu, Marc Henneaux +1
The BRST Noether theorem, or ``Noether's 1.5 theorem'', asserts the triviality of the BRST Noether current. We provide two proofs of this theorem that are both valid without restri…
Exact WKB in all sectors II: Potentials with non-degenerate saddles
Tatsuhiro Misumi, Cihan Pazarbaşı
We discuss the exact quantization of general one-dimensional potentials in view of the exact-WKB formalism. Building on our previous work, we perform analytic continuations across…
Massive Higher Spins and Black Hole Interactions
Julian Lang, Mirian Tsulaia
We give a brief introduction into the gauge invariant formulation of irreducible massive bosonic higher spin fields. We discuss both free Lagrangians and the ones which include cub…
Universal sectors of two-dimensional Carrollian CFTs
Ankit Aggarwal, Arjun Bagchi, Stephane Detournay +3
We revisit modular invariance in two-dimensional Carrollian conformal field theories from a geometric perspective. Focusing on the characters of the induced and highest-weight repr…
Krylov operator complexity in holographic CFTs: Smeared boundary reconstruction and the dual proper radial momentum
Sergio E. Aguilar-Gutierrez, Hugo A. Camargo, Viktor Jahnke +2
Motivated by bulk reconstruction of smeared boundary operators, we study the Krylov complexity of local and non-local primary CFT operators from the local bulk-to-bulk propagat…
Diagonalization Procedure for Reducible Massless N=1 Supermultiplets
Keith Glennon, Mirian Tsulaia
We consider N=1 supersymmetric systems in d=4, 6 and 10 dimensions which consist of reducible bosonic and fermionic massless representations of the Poincare group. We show in detai…
Crossed products and quantum reference frames: on the observer-dependence of gravitational entropy
Julian De Vuyst, Stefan Eccles, Philipp A. Hoehn +1
A significant step towards a rigorous understanding of perturbative gravitational entropy was recently achieved by a series of works showing that a proper accounting of gauge invar…
Soft edges: the many links between soft and edge modes
Goncalo Araujo-Regado, Philipp A. Hoehn, Francesco Sartini +1
Boundaries in gauge theory and gravity give rise to symmetries and charges at both finite and asymptotic distance. Due to their structural similarities, it is often held that soft…
Linearization (in)stabilities and crossed products
Julian De Vuyst, Stefan Eccles, Philipp A. Hoehn +1
Modular crossed product algebras have recently assumed an important role in perturbative quantum gravity as they lead to an intrinsic regularization of entanglement entropies by in…
Exact WKB in all sectors I: Potentials with degenerate saddles
Tatsuhiro Misumi, Cihan Pazarbaşı
We explore the exact-WKB (EWKB) method through the analysis of Airy and Weber types, with an emphasis on the exact quantization of locally harmonic potentials in multiple sectors.…
Holography and the Hilbert Scheme
Samuel Crew, Daniel Zhang, Ziruo Zhang
We elucidate a holographic relationship between the enumerative geometry of the Hilbert scheme of points in the plane , with large, and the entropy of certain…
Gravitational entropy is observer-dependent
Julian De Vuyst, Stefan Eccles, Philipp A. Hoehn +1
In quantum gravity, it has been argued that a proper accounting of the role played by an observer promotes the von Neumann algebra of observables in a given spacetime subregion fro…
Hofstadter-Toda spectral duality and quantum groups
Pasquale Marra, Valerio Proietti, Xiaobing Sheng
The Hofstadter model allows to describe and understand several phenomena in condensed matter such as the quantum Hall effect, Anderson localization, charge pumping, and flat-bands…
Holographic Screen Sequestration
Aidan Chatwin-Davies, Pompey Leung, Grant N. Remmen
Holographic screens are codimension-one hypersurfaces that extend the notion of apparent horizons to general (non-black hole) spacetimes and that display interesting thermodynamic…
Carroll black holes
Florian Ecker, Daniel Grumiller, Jelle Hartong +3
Despite the absence of a lightcone structure, some solutions of Carroll gravity show black hole-like behaviour. We define Carroll black holes as solutions of Carroll gravity that e…
Quartic locality of higher-spin gravity in de Sitter and Euclidean anti-de Sitter space
Yasha Neiman
We consider higher-spin gravity in (A)dS_4, defined as the holographic dual of a free O(N) or Sp(N) vector model. At the quartic level, this theory has been judged non-local at dis…
Magic Fermions: Carroll and Flat Bands
Arjun Bagchi, Aritra Banerjee, Rudranil Basu +2
The Carroll algebra is constructed as the limit of the Poincare algebra and is associated to symmetries on generic null surfaces. In this paper, we begin investigations of…
Carroll fermions in two dimensions
Aritra Banerjee, Sudipta Dutta, Saikat Mondal
Carroll symmetry is a very powerful characteristic of generic null surfaces, as it replaces the usual Poincaré algebra with a vanishing speed of light version thereof. These symmet…
Scaling solutions for asymptotically free quantum gravity
Saswato Sen, Christof Wetterich, Masatoshi Yamada
We compute scaling solutions of functional flow equations for quantum gravity in a general truncation with up to four derivatives of the metric. They connect the asymptotically fre…
Horizon Strings as 3d Black Hole Microstates
Arjun Bagchi, Daniel Grumiller, M. M. Sheikh-Jabbari
We propose that 3d black holes are an ensemble of tensionless null string states. These microstates typically have non-zero winding. We evaluate their partition function in the lim…
Emergent classical gauge symmetry from quantum entanglement
Josh Kirklin
We describe explicitly how entanglement between quantum mechanical subsystems can lead to emergent gauge symmetry in a classical limit. We first provide a precise characterisation…
Supersymmetric Quantum Chiral Higher Spin Gravity
Mirian Tsulaia, Dorin Weissman
We study quantum properties of supersymmetric N=1 and N=4 extensions of the four dimensional bosonic Chiral Higher Spin Gravities (HiSGRAs). We discuss the spectra, the classical a…
New diagrammatic framework for higher-spin gravity
Yasha Neiman
We consider minimal type-A higher-spin (HS) gravity in four dimensions, at tree level. We propose new diagrammatic rules for this theory, involving both Fronsdal fields and Didenko…
