Duality and Global Symmetries [PDF]

Nuclear Physics B - Proceedings Supplements, 1997
This is a general introduction to duality in field theories. The existence and breaking of global symmetries is used as a guideline to systematically prove duality between different field theories.

Classifying global symmetries of 6D SCFTs [PDF]

Journal of High Energy Physics, 2018
We characterize the global symmetries for the conjecturally complete collection of all six dimensional superconformal field theories (6D SCFTs) which are realizable in F-theory and have no frozen singularities.

2-Group global symmetries and anomalies in six-dimensional quantum field theories [PDF]

Journal of High Energy Physics, 2021
We examine six-dimensional quantum field theories through the lens of higher-form global symmetries. Every Yang-Mills gauge theory in six dimensions, with field strength f (2), naturally gives rise to a continuous 1-form global symmetry associated with ...

On 2-group global symmetries and their anomalies [PDF]

Journal of High Energy Physics, 2019
In general quantum field theories (QFTs), ordinary (0-form) global symmetries and 1-form symmetries can combine into 2-group global symmetries. We describe this phenomenon in detail using the language of symmetry defects. We exhibit a simple procedure to

Comments on global symmetries, anomalies, and duality in (2 + 1)d [PDF]

Journal of High Energy Physics, 2017
We analyze in detail the global symmetries of various (2 + 1)d quantum field theories and couple them to classical background gauge fields. A proper identification of the global symmetries allows us to consider all non-trivial bundles of those background

Constraints on discrete global symmetries in quantum gravity [PDF]

Journal of High Energy Physics, 2021
The question whether global symmetries can be realized in quantum-gravity-matter-systems has far-reaching phenomenological consequences. Here, we collect evidence that within an asymptotically safe context, discrete global symmetries of the form ℤ n , n >

Global symmetries of quantum lattice models under non-invertible dualities

SciPost Physics Core
Non-invertible dualities/symmetries have become an important tool in the study of quantum field theories and quantum lattice models in recent years. One of the most studied examples is non-invertible dualities obtained by gauging a discrete group.

2-group global symmetries, hydrodynamics and holography [PDF]

SciPost Physics, 2023
2-group global symmetries are a particular example of how higher-form and conventional global symmetries can fuse together into a larger structure. We construct a theory of hydrodynamics describing the finite-temperature realization of a 2-group global ...

Strongly Interacting Light Dark Matter [PDF]

SciPost Physics, 2017
In the presence of approximate global symmetries that forbid relevant interactions, strongly coupled light Dark Matter (DM) can appear weakly coupled at small energy and generate a sizable relic abundance.

Global Symmetries in the Antifield-Formalism [PDF]

Physics Letters B, 1996
In this paper, two things are done. (i) First, it is shown that any global symmetry of a gauge-invariant theory can be extended to the ghosts and the antifields so as to leave invariant the solution of the master-equation (before gauge fixing).
