Counting Nambu-Goldstone Modes of Higher-Form Global Symmetries. [PDF]
Physical Review Letters, 2020 We discuss the counting of Nambu-Goldstone (NG) modes associated with the spontaneous breaking of higher-form global symmetries. Effective field theories of NG modes are developed based on symmetry-breaking patterns, using a generalized coset ...

Quantum Carroll/fracton particles
Journal of High Energy Physics, 2023 We classify and relate unitary irreducible representations (UIRs) of the Carroll and dipole groups, i.e., we define elementary quantum Carroll and fracton particles and establish a correspondence between them.

Topological violation of global symmetries in quantum gravity [PDF]
Journal of High Energy Physics, 2020 We discuss a topological reason why global symmetries are not conserved in quantum gravity, at least when the symmetry comes from compactification of a higher form symmetry.

Actions and symmetries of NSR superstrings and D-strings [PDF]
, 2000 We present all NSR superstring and super-D-string actions invariant under a set of prescribed gauge transformations, and characterize completely their global symmetries.

Sterile neutrinos and global symmetries [PDF]
Physical Review D, 2005 We use an effective-field-theory approach to construct models with naturally light sterile neutrinos, due to either exact or accidental global symmetries. The most attractive models we find are based on gauge symmetries, either discrete or continuous. We give examples of simple models based on Z_N, U(1)', and SU(2)'.

A particle model with extra dimensions from coadjoint Poincaré symmetry
Journal of High Energy Physics, 2020 Starting from the coadjoint Poincaré algebra we construct a point particle relativistic model with an interpretation in terms of extra-dimensional variables.

Dyson’s classification and real division superalgebras
Journal of High Energy Physics, 2021 It is well-known that unitary irreducible representations of groups can be usefully classified in a 3-fold classification scheme: Real, Complex, Quaternionic.

A violation of global symmetries from replica wormholes and the fate of black hole remnants [PDF]
, 2020 We show that the presence of replica wormholes in the Euclidean path integral of gravity leads to a non-perturbative violation of charge conservation for any global symmetry present in the low-energy description of quantum gravity. Explicitly, we compute

Non-invertible symmetries from discrete gauging and completeness of the spectrum
Journal of High Energy Physics, 2023 We study global 1- and (d − 2)-form symmetries for gauge theories based on disconnected gauge groups which include charge conjugation. For pure gauge theories, the 1-form symmetries are shown to be non-invertible.

Lifting M-theory to Two-Time Physics [PDF]
, 1999 M-theory has different global supersymmetry structures in its various dual incarnations, as characterized by the M-algebra in 11D, the type IIA, type-IIB, heterotic, type-I extended supersymmetries in 10D, and non-Abelian supersymmetries in the AdS_n x S^
