A note on unfree gauge symmetry [PDF]

open access: yesNuclear Physics B, 2019
We study the general structure of field theories with the unfree gauge symmetry where the gauge parameters are restricted by differential equations.

Unfree gauge symmetry [PDF]

open access: yesarXiv, 2023
The gauge symmetry is said unfree if the gauge transformation leaves the action functional unchanged provided for the gauge parameters are constrained by the system of partial differential equations. The best known example of this phenomenon is the volume preserving diffeomorphism being the gauge symmetry of unimodular gravity (UG).

Reducible gauge symmetry versus unfree gauge symmetry in Hamiltonian formalism [PDF]

open access: yesNuclear Physics B, 2021
The unfree gauge symmetry implies that gauge variation of the action functional vanishes provided for the gauge parameters are restricted by the differential equations.

Poincaré gauge symmetries, hamiltonian symmetries and trivial gauge transformations [PDF]

open access: yesPhys.Rev.D84:124034,2011, 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.

Non-invertible symmetries from discrete gauging and completeness of the spectrum [PDF]

open access: yesJournal 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.

Parity from gauge symmetry

open access: yesEuropean 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 ...

Gauge fixing and physical symmetries [PDF]

open access: yesarXiv, 2023
We analyze how gauge fixing, which is required by any practical continuum approach to gauge systems, can interfere with the physical symmetries of such systems. In principle, the gauge fixing procedure, which deals with the (unphysical) gauge symmetry, should not interfere with the other (physical) symmetries.

Gauge symmetry from decoupling

open access: yesNuclear Physics B, 2017
Gauge symmetries emerge from a redundant description of the effective action for light degrees of freedom after the decoupling of heavy modes. This redundant description avoids the use of explicit constraints in configuration space.

Operator Gauge Symmetry in QED [PDF]

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2006
In this paper, operator gauge transformation, first introduced by Kobe, is applied to Maxwell's equations and continuity equation in QED. The gauge invariance is satisfied after quantization of electromagnetic fields.
