Invariants of broken discrete symmetries. [PDF]

Physical Review Letters, 2014
The parity and Bloch theorems are generalized to the case of broken global symmetry. Local inversion or translation symmetries in one dimension are shown to yield invariant currents that characterize wave propagation. These currents map the wave function

Dark Discrete Gauge Symmetries [PDF]

Physical Review D, 2010
We investigate scenarios in which dark matter is stabilized by an abelian Z_N discrete gauge symmetry. Models are surveyed according to symmetries and matter content.

Flavor, CP and metaplectic modular symmetries in Type IIB chiral flux vacua

Journal of High Energy Physics, 2023
We examine symmetries of chiral four-dimensional vacua of Type IIB flux compactifications with vanishing superpotential W = 0. We find that the N $$ \mathcal{N} $$ = 1 supersymmetric MSSM-like and Pati-Salam vacua possess enhanced discrete symmetries in ...

Yukawas and discrete symmetries in F-theory compactifications without section [PDF]

, 2014
A bstractIn the case of F-theory compactifications on genus-one fibrations without section there are naturally appearing discrete symmetries, which we argue to be associated to geometrically massive U(1) gauge symmetries.

Anomalous discrete symmetries in three dimensions and group cohomology. [PDF]

Physical Review Letters, 2014
We study 't Hooft anomalies for a global discrete internal symmetry G. We construct examples of bosonic field theories in three dimensions with a nonvanishing 't Hooft anomaly for a discrete global symmetry.

Note on gauge and gravitational anomalies of discrete Z N symmetries

Journal of High Energy Physics, 2018
In this note, we discuss the consistency conditions which a discrete Z N symmetry should satisfy in order that it is not violated by gauge and gravitational instantons.

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.

ON PARTIAL DIFFERENTIAL AND DIFFERENCE EQUATIONS WITH SYMMETRIES DEPENDING ON ARBITRARY FUNCTIONS

Acta Polytechnica, 2016
In this note we present some ideas on when Lie symmetries, both point and generalized, can depend on arbitrary functions. We show a few examples, both in partial differential and partial difference equations where this happens.

(Non-)Abelian discrete anomalies

, 2008
We derive anomaly constraints for Abelian and non-Abelian discrete symmetries using the path integral approach. We survey anomalies of discrete symmetries in heterotic orbifolds and find a new relation between such anomalies and the so-called `anomalous'

Discrete Gauge Symmetries in Discrete MSSM-like Orientifolds [PDF]

, 2012
Motivated by the necessity of discrete Z_N symmetries in the MSSM to insure baryon stability, we study the origin of discrete gauge symmetries from open string sector U(1)'s in orientifolds based on rational conformal field theory.
