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…
Bulk locality and gauge invariance for boundary-bilocal cubic correlators in higher-spin gravity
Vyacheslav Lysov, Yasha Neiman
We consider type-A higher-spin gravity in 4 dimensions, holographically dual to a free O(N) vector model. In this theory, the cubic correlators of higher-spin boundary currents are…
Measure for chaotic scattering amplitudes
Massimo Bianchi, Maurizio Firrotta, Jacob Sonnenschein +1
We propose a novel measure of chaotic scattering amplitudes. It takes the form of a log-normal distribution function for the ratios of (consecutive) spacings…
Higher-spin gravity's "string": new gauge and proof of holographic duality for the linearized Didenko-Vasiliev solution
Vyacheslav Lysov, Yasha Neiman
We consider type-A higher-spin gravity in AdS_4, holographically dual to a free U(N) vector model on the boundary. We study the linearized version of the Didenko-Vasiliev "BPS blac…
Operational islands and black hole dissipation in JT gravity
Julian De Vuyst, Thomas G. Mertens
In this work, we revisit the problem of finding entanglement islands in 2d Jackiw-Teitelboim (JT) gravity. We implement the following adjustments to the traditional setup: (1) we d…
From CFTs to theories with Bondi-Metzner-Sachs symmetries: Complexity and out-of-time-ordered correlators
Aritra Banerjee, Arpan Bhattacharyya, Priya Drashni +1
We probe the contraction from relativistic CFTs to theories with Bondi-Metzner-Sachs (BMS) symmetries, or equivalently Conformal Carroll symmetries, using diagnostics of quant…
Boosting to BMS
Arjun Bagchi, Aritra Banerjee, Hisayoshi Muraki
Bondi-Metzner-Sachs (BMS) symmetries, or equivalently Conformal Carroll symmetries, are intrinsically associated to null manifolds and in two dimensions can be obtained as an In{ö}…
Edge modes as dynamical frames: charges from post-selection in generally covariant theories
Sylvain Carrozza, Stefan Eccles, Philipp A. Hoehn
We develop a framework based on the covariant phase space formalism that identifies gravitational edge modes as dynamical reference frames. They enable the identification of the as…
Tropical Mirror
Andrey Losev, Vyacheslav Lysov
We describe the tropical curves in toric varieties and define the tropical Gromov-Witten invariants. We introduce amplitudes for the higher topological quantum mechanics (HTQM) on…
Disorder in AdS/CFT
Moritz Dorband, Daniel Grumiller, René Meyer +1
We perturbatively study marginally relevant quenched disorder in AdS/CFT to second order in the disorder strength. Using the Chern-Simons formulation of AdS gravity for…
Carroll covariant scalar fields in two dimensions
Arjun Bagchi, Aritra Banerjee, Sudipta Dutta +2
Conformal Carroll symmetry generically arises on null manifolds and is important for holography of asymptotically flat spacetimes, generic black hole horizons and tensionless strin…
