Dark matter and global symmetries
Physics Letters B, 2016 General considerations in general relativity and quantum mechanics are known to potentially rule out continuous global symmetries in the context of any consistent theory of quantum gravity.

Quantum groups as global symmetries
Journal of High Energy PhysicsWe study quantum field theories which have quantum groups as global internal symmetries. We show that in such theories operators are generically non-local, and should be thought as living at the ends of topological lines.

Noninvertible Global Symmetries in the Standard Model. [PDF]
Physical Review Letters, 2022 We identify infinitely many noninvertible generalized global symmetries in QED and QCD for the real world in the massless limit. In QED, while there is no conserved Noether current for the U(1)_{A} axial symmetry because of the Adler-Bell-Jackiw anomaly,

Factorization and global symmetries in holography [PDF]
SciPost Physics, 2022 We consider toy models of holography arising from 3d Chern-Simons theory. In this context a duality to an ensemble average over 2d CFTs has been recently proposed. We put forward an alternative approach in which, rather than summing over bulk geometries,

Global symmetries and effective potential of 2HDM in orbit space [PDF]
Physical Review D, 2023 We extend the framework of analyzing the 2HDM in its orbit space to study the one-loop effective potential before and after electroweak symmetry breaking. In this framework, we present a comprehensive analysis of global symmetries of the one-loop thermal

Global Symmetries, Code Ensembles, and Sums over Geometries. [PDF]
Physical Review Letters, 2023 We consider Abelian topological quantum field theories (TQFTs) in 3D and show that gaugings of invertible global symmetries naturally give rise to additive codes.

Non-invertible global symmetries and completeness of the spectrum [PDF]
Journal of High Energy Physics, 2021 It is widely believed that consistent theories of quantum gravity satisfy two basic kinematic constraints: they are free from any global symmetry, and they contain a complete spectrum of gauge charges.

Broken Global Symmetries and Defect Conformal Manifolds. [PDF]
Physical Review Letters, 2022 Just as exactly marginal operators allow one to deform a conformal field theory along the space of theories known as the conformal manifold, appropriate operators on conformal defects allow for deformations of the defects.

Protecting local and global symmetries in simulating 1+1-D non-abelian gauge theories [PDF]
, 2022 Efficient quantum simulation protocols for any quantum theories demand efficient protection protocols for its underlying symmetries. This task is nontrivial for gauge theories as it is involves local symmetry/invariance.
