Higher-form symmetries of 6d and 5d theories
Journal of High Energy Physics, 2021 We describe general methods for determining higher-form symmetry groups of known 5d and 6d superconformal field theories (SCFTs), and 6d little string theories (LSTs).

Many-body Majorana-like zero modes without gauge symmetry breaking
Physical Review Research, 2021 Topological superconductors represent one of the key hosts of Majorana-based topological quantum computing. Typical scenarios for one-dimensional (1D) topological superconductivity assume a broken gauge symmetry associated to a superconducting state ...

(p − 1)-bracket for Dp-branes in large R-R field background
Journal of High Energy Physics, 2023 The volume-preserving diffeomorphism is a key feature that characterizes the large constant R-R (p − 1)-form field background in a Dp-brane theory. It represents a symmetry of the theory that preserves the volume of space.

When ℤ2 one-form symmetry leads to non-invertible axial symmetries
Journal of High Energy Physics, 2023 We study non-abelian gauge theories with fermions in a representation such that the surviving electric 1-form symmetry is ℤ2. This includes SU(N) gauge theories with matter in the (anti)symmetric and N even, and USp(2N) with a Weyl fermion in the adjoint,

Symmetry and the Metaphysics of Physics [PDF]
, 2010 The widely held picture of dynamical symmetry as surplus structure in a physical theory has many metaphysical applications. Here I focus on its relevance to the question of which quantities in a theory represent fundamental natural ...

Are gauge symmetry transformations observable? [PDF]
, 2003 In a recent paper in the British Journal for the Philosophy of Science, Kosso discussed the observational status of continuous symmetries of physics. While we are in broad agreement with his approach, we disagree with his analysis.

4d/2d Correspondence: Instantons and W-Algebras [PDF]
, 2012 In this thesis, we study the 4d/2d correspondence of Alday-Gaiotto-Tachikawa, which relates the class of 4-dimensional N=2 gauge theories (theories of class S) to a 2-dimensional conformal field theory. The 4d gauge theories are obtained by compactifying

Symmetric Gapped Interfaces of SPT and SET States: Systematic Constructions
Physical Review X, 2018 Symmetry-protected topological (SPT) states have boundary ’t Hooft anomalies that obstruct the effective boundary theory realized in its own dimension with UV completion and with an on-site G-symmetry.

Abelian combinatorial gauge symmetry
SciPost Physics CoreCombinatorial gauge symmetry is a principle that allows us to construct lattice gauge theories with two key and distinguishing properties: a) only one- and two-body interactions are needed; and b) the symmetry is exact rather than emergent in an ...
