Discrete Lorentz symmetry and discrete time translational symmetry
New Journal of Physics, 2018 The Lorentz symmetry and the space and time translational symmetry are fundamental symmetries of nature. Crystals are the manifestation of the continuous space translational symmetry being spontaneously broken into a discrete one.

Discrete symmetries in dimer diagrams [PDF]
Journal of High Energy Physics, 2019 We apply dimer diagram techniques to uncover discrete global symmetries in the fields theories on D3-branes at singularities given by general orbifolds of general toric Calabi-Yau threefold singularities.

Non-linearly realized discrete symmetries
Journal of High Energy Physics, 2020 While non-linear realizations of continuous symmetries feature derivative interactions and have no potential, non-linear realizations of discrete symmetries feature non-derivative interactions and have a highly suppressed potential.

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

CP and discrete flavour symmetries [PDF]
Journal of High Energy Physics, 2013 We give a consistent definition of generalised CP transformations in the context of discrete flavour symmetries. Non-trivial consistency conditions imply that every generalised CP transformation can be interpreted as a representation of an automorphism of the discrete group.

2-Group symmetries and their classification in 6d
SciPost Physics, 2022 We uncover 2-group symmetries in 6d superconformal field theories. These symmetries arise when the discrete 1-form symmetry and continuous flavor symmetry group of a theory mix with each other.

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 are shown to yield invariant currents that characterize wave propagation. These currents map the wave function from an arbitrary spatial domain to any symmetry-related domain.

Discrete R symmetries and anomalies [PDF]
Journal of High Energy Physics, 2014 We comment on aspects of discrete anomaly conditions focussing particularly on $R$ symmetries. We review the Green-Schwarz cancellation of discrete anomalies, providing a heuristic explanation why, in the heterotic string, only the "model-independent dilaton" transforms non-linearly under discrete symmetries; this argument suggests that, in other ...

Evolution of discrete symmetries
Physical Review E, 2023 Symmetries are known to dictate important physical properties and can be used as a design principle in particular in wave physics, including wave structures and the resulting propagation dynamics. Local symmetries, in the sense of a symmetry that holds only in a finite domain of space, can be either the result of a self-organization process or a ...

Tests of discrete symmetries in positronium decays with the J-PET detector [PDF]
EPJ Web of Conferences, 2019 As a relatively simple and purely leptonic state positronium constitutes a unique system to study discrete symmetries with precision limited only by the effects due to the weak interaction and photon-photon scattering.
