Gauge-Symmetry Protection Using Single-Body Terms [PDF]
PRX Quantum, 2020 Quantum-simulator hardware promises new insights into problems from particle and nuclear physics. A major challenge is to reproduce gauge invariance, as violations of this quintessential property of lattice gauge theories can have dramatic consequences ...

Journal of High Energy Physics, 2023 Abstract The tadpole conjecture proposes that complex structure moduli stabilisation by fluxes that have low tadpole charge can be realised only at special points in moduli space, leading generically to (large) gauge symmetries. Here we provide an exhaustive survey of the gauge symmetries arising in F-theory flux compactifications ...

Discrete theta angles, symmetries and anomalies
SciPost Physics, 2021 Gauge theories in various dimensions often admit discrete theta angles, that arise from gauging a global symmetry with an additional symmetry protected topological (SPT) phase.

International Journal of Modern Physics A, 2003 We propose a new procedure to embed second class systems by introducing Wess–Zumino (WZ) fields in order to unveil hidden symmetries existent in the models. This formalism is based on the direct imposition that the new Hamiltonian must be invariant by gauge-symmetry transformations.

Hamiltonian constraints and unfree gauge symmetry [PDF]
, 2020 We study Hamiltonian form of unfree gauge symmetry where the gauge parameters have to obey differential equations. We consider the general case such that the Dirac-Bergmann algorithm does not necessarily terminate at secondary constraints, and tertiary ...

European Physical Journal C: Particles and Fields, 2022 We argue that Left-Right parity symmetry $${\mathcal {P}}$$ P can arise as a discrete remnant of a unified gauge symmetry. The high-energy unification necessarily includes the gauging of the Lorentz symmetry, bringing into the game gravitational ...

Poincaré gauge symmetries, Hamiltonian symmetries, and trivial gauge transformations [PDF]
Physical Review D, 2011 We resolve a problem of finding the Poincare symmetries from hamiltonian gauge symmetries constructed through a canonical procedure of handling constrained systems. Through the use of Noether identities corresponding to the symmetries, we motivate a procedure of finding the map between the hamiltonian and Poincare gauge parameters.

Doubled aspects of Vaisman algebroid and gauge symmetry in double field theory [PDF]
Journal of Mathematics and Physics, 2019 The metric algebroid proposed by Vaisman (the Vaisman algebroid) governs the gauge symmetry algebra generated by the C-bracket in double field theory (DFT).

Symmetry-enriched quantum spin liquids in (3 + 1)d
Journal of High Energy Physics, 2020 We use the intrinsic one-form and two-form global symmetries of (3+1)d bosonic field theories to classify quantum phases enriched by ordinary (0-form) global symmetry. Different symmetry-enriched phases correspond to different ways of coupling the theory
