Linking entanglement and discrete anomaly
Journal of High Energy Physics, 2018 In 3d Chern-Simons theory, there is a discrete one-form symmetry, whose symmetry group is isomorphic to the center of the gauge group. We study the ‘t Hooft anomaly associated to this discrete one-form symmetry in theories with generic gauge groups, A, B,

Dai-Freed anomaly in the standard model and topological inflation
Journal of High Energy Physics, 2023 When we impose discrete symmetries in the standard model we have Dai-Freed global anomalies. However, interestingly if we introduce three right-handed neutrinos we can have an anomaly-free discrete Z 4 gauge symmetry.

Phenomenological implications of a minimal F-theory GUT with discrete symmetry [PDF]
, 2015 A bstractWe discuss the origin of both non-Abelian discrete family symmetry and Abelian continuous family symmetry, as well as matter parity, from F-theory SUSY GUTs. We propose a minimal model based on the smallest GUT group SU(5), together with the non-

Scotogenic A5 → A4 Dirac neutrinos with freeze-in dark matter
Physics Letters B, 2022 Radiative Dirac neutrino masses and their mixing are linked to dark matter through the non-Abelian discrete symmetry A5 of the 4-dimensional pentatope, softly broken to A4 of the 3-dimensional tetrahedron.

Anomalous discrete flavor symmetry and domain wall problem
Physics Letters B, 2019 Discrete flavor symmetry is often introduced for explaining quark/lepton masses and mixings. However, its spontaneous breaking leads to the appearance of domain walls, which is problematic for cosmology. We consider a possibility that the discrete flavor

Discrete Rotational Symmetry and Quantum Key Distribution Protocols [PDF]
, 2006 We study the role of discrete rotational symmetry in quantum key distribution by generalizing the well-known Bennett-Brassard 1984 (BB84) and Scarani-Acin-Ribordy-Gisin 2004 (SARG04) protocols.

Discrete spin structures and commuting projector models for two-dimensional fermionic symmetry-protected topological phases [PDF]
, 2016 We construct exactly solved commuting projector Hamiltonian lattice models for all known 2+1d fermionic symmetry protected topological phases (SPTs) with on-site unitary symmetry group $G_f = G \times \mathbb{Z}_2^f$, where $G$ is finite and $\mathbb{Z ...

CP Symmetry and Lepton Mixing from a Scan of Finite Discrete Groups [PDF]
, 2016 Including the generalized CP symmetry, we have performed a comprehensive scan of leptonic mixing patterns which can be obtained from finite discrete groups with order less than 2000. Both the semidirect approach and its variant are considered. The lepton
