Entanglement entropy and superselection sectors. Part I. Global symmetries [PDF]

Journal of High Energy Physics, 2019
Some quantum field theories show, in a fundamental or an effective manner, an alternative between a loss of duality for algebras of operators corresponding to complementary regions, or a loss of additivity.

Quaternion-Octonion Unitary Symmetries and Analogous Casimir Operators [PDF]

, 2012
An attempt has been made to investigate the global SU(2) and SU(3) unitary flavor symmetries systematically in terms of quaternion and octonion respectively.

High energy modular bootstrap, global symmetries and defects [PDF]

Journal of High Energy Physics, 2020
We derive Cardy-like formulas for the growth of operators in different sectors of unitary 2 dimensional CFT in the presence of topological defect lines by putting an upper and lower bound on the number of states with scaling dimension in the interval [∆ −

Non-invertible Gauss law and axions

Journal of High Energy Physics, 2023
In axion-Maxwell theory at the minimal axion-photon coupling, we find non-invertible 0- and 1-form global symmetries arising from the naive shift and center symmetries.

Mixed anomalies, two-groups, non-invertible symmetries, and 3d superconformal indices

Journal of High Energy Physics, 2023
Mixed anomalies, higher form symmetries, two-group symmetries and non-invertible symmetries have proved to be useful in providing non-trivial constraints on the dynamics of quantum field theories.

Discrete and higher-form symmetries in SCFTs from wrapped M5-branes

Journal of High Energy Physics, 2021
We analyze topological mass terms of BF type arising in supersymmetric M-theory compactifications to AdS 5. These describe spontaneously broken higher-form gauge symmetries in the bulk. Different choices of boundary conditions for the BF terms yield dual

Note on Discrete Gauge Anomalies

, 1991
We consider the probem of gauging discrete symmetries. All valid constraints on such symmetries can be understood in the low energy theory in terms of instantons.

Ghost Cohomologies and Hidden Space-Time Symmetries [PDF]

, 2007
We observe and study new non-linear global space-time symmetries of the full ghost+matter action of RNS superstring theory. We show that these surprising new symmetries are generated by the special worldsheet currents (vertex operators) of RNS ...

Comments on one-form global symmetries and their gauging in 3d and 4d [PDF]

SciPost Physics, 2018
We study 3d and 4d systems with a one-form global symmetry, explore their consequences, and analyze their gauging. For simplicity, we focus on \mathbb{Z}_NℤN one-form symmetries.

Global Anomalies in the Batalin Vilkovisky Quantization [PDF]

, 1996
The Batalin Vilkovisky (BV) quantization provides a general procedure for calculating anomalies associated to gauge symmetries. Recent results show that even higher loop order contributions can be calculated by introducing an appropriate regularization ...
