Genus-One Rigidity of Bounded Virasoro Pairings for 3D Gravity
Xingyang Yu
Motivated by the proposed relation between 3D gravity and the doubled Virasoro TQFT, and by the associated program of ensemble holography, we ask whether ensemble holography in AdS…
Notes on (-2)-form symmetries
Pinak Banerjee, Alonso Perez-Lona, Daniel Robbins +3
The paper introduces and analyzes (-2)-form symmetries in quantum field theories via a (-1)-form symmetry of the associated Symmetry Topological Field Theory, showing how they modi…
From Baby Universes to Narain Moduli: Topological Boundary Averaging in SymTFTs
Xingyang Yu
Building on the viewpoint that ensemble averages in TQFT gravity can be organized by topological boundary data, we develop a SymTFT interpretation of ensemble averaging in low-dime…
A Linearized Obstruction to the Supersymmetric Extension of Conformal Boundary Conditions in Euclidean Gravity
Xingyang Yu
The conformal boundary condition for gravity fixes the boundary conformal class and the mean curvature, leaving the trace-free extrinsic curvature free as the conjugate response. I…
On the SymTFTs of Finite Non-Abelian Symmetries
Oren Bergman, Jonathan J. Heckman, Max Hübner +3
The -dimensional symmetry topological field theory (SymTFT) of a -dimensional absolute quantum field theory (QFT) provides a topological characterization of s…
Total instanton restriction via multiverse interference: Noncompact gauge theories and (-1)-form symmetries
Alonso Perez-Lona, Eric Sharpe, Xingyang Yu +1
In this note we consider examples of decomposition (in which a local QFT is equivalent to a disjoint union of multiple independent theories, known as universes) where there is a co…
