Magnetic Higher-Form Symmetries as Dual Fundamental -Groupoids
Alonso Perez-Lona
We develop a higher-geometric framework for magnetic higher-form symmetries of pre-quantum field theories. The magnetic (topological) charges of a sigma-model with stacky target ar…
Notes on (-2)-form symmetries
Pinak Banerjee, Alonso Perez-Lona, Daniel Robbins +3
We study -form symmetries of a -dimensional quantum field theory, via a -form symmetry of its -dimensional Symmetry Topological Field Theory (SymTFT), realize…
Higher-form symmetries as higher automorphism bundles
Alonso Perez-Lona
The notion of global higher-form symmetries has received much attention, but leaves room for a more systematic mathematical formulation. In this article, we highlight the concept o…
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…
Decomposition in 2d non-invertible gaugings
Alonso Perez-Lona
We extend the decomposition conjecture to 2d quantum field theories with a gauged symmetry category for a finite-dimensional semisimple Hopf algebra with $\text…
Notes on gauging noninvertible symmetries, part 2: higher multiplicity cases
Alonso Perez-Lona, Daniel Robbins, Eric Sharpe +2
In this paper we discuss gauging noninvertible zero-form symmetries in two dimensions, extending our previous work. Specifically, in this work we discuss more general gauged noninv…
Discrete torsion in gauging non-invertible symmetries
Alonso Perez-Lona
In this paper we discuss generalizations of discrete torsion to noninvertible symmetries in 2d QFTs. One point of this paper is to explain that there are two complementary generali…
Notes on gauging noninvertible symmetries, part 1: Multiplicity-free cases
A. Perez-Lona, D. Robbins, E. Sharpe +2
In this paper we discuss gauging noninvertible zero-form symmetries in two dimensions. We specialize to certain gaugeable cases, specifically, fusion categories of the form Rep(H)…
Three-dimensional orbifolds by 2-groups
Alonso Perez-Lona, Eric Sharpe
In this paper we generalize previous work on decomposition in three-dimensional orbifolds by 2-groups realized as analogues of central extensions, to orbifolds by more general 2-gr…
