Operator Gauge Symmetry in QED [PDF]
Symmetry, 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.

Reparametrization Invariance as Gauge Symmetry [PDF]
International Journal of Theoretical Physics, 1998 Reparametrization invariance being treated as a gauge symmetry shows some specific peculiarities. We study these peculiarities both from a general point of view and on concrete examples. We consider the canonical treatment of reparametrization invariant systems in which one fixes the gauge on the classical level by means of time-dependent gauge ...

Suppressing nonperturbative gauge errors in the thermodynamic limit using local pseudogenerators [PDF]
Communications PhysicsWith recent progress in quantum simulations of lattice-gauge theories, it is becoming a pressing question how to reliably protect the gauge symmetry that defines such models.

Kerr Black Holes from Massive Higher-Spin Gauge Symmetry. [PDF]
Physical Review Letters, 2022 We propose that the dynamics of Kerr black holes is strongly constrained by the principle of gauge symmetry. We initiate the construction of effective field theories for Kerr black holes of any integer quantum spin s using Stückelberg fields, and show ...

Quantum Nonreciprocal Interactions via Dissipative Gauge Symmetry [PDF]
PRX Quantum, 2022 One-way nonreciprocal interactions between two quantum systems are typically described by a cascaded quantum master equation, and rely on an effective breaking of time-reversal symmetry as well as the balancing of coherent and dissipative interactions ...

Global dipole symmetry, compact Lifshitz theory, tensor gauge theory, and fractons [PDF]
Physical review B, 2022 We study field theories with global dipole symmetries and gauge dipole symmetries. The famous Lifshitz theory is an example of a theory with a global dipole symmetry. We study in detail its 1+1d version with a compact field.

Holographic symmetry algebras for gauge theory and gravity [PDF]
Journal of High Energy Physics, 2021 All 4D gauge and gravitational theories in asymptotically flat spacetimes contain an infinite number of non-trivial symmetries. They can be succinctly characterized by generalized 2D currents acting on the celestial sphere.

Volume-preserving diffeomorphism as nonabelian higher-rank gauge symmetry [PDF]
SciPost Physics, 2021 We propose nonabelian higher-rank gauge theories in 2+1D and 3+1D. The gauge group is constructed from the volume-preserving diffeomorphisms of space. We show that the intriguing physics of the lowest Landau level (LLL) limit can be interpreted as the ...

Lattice gauge theories in the presence of a linear gauge-symmetry breaking. [PDF]
Physical Review E, 2021 We study the effects of gauge-symmetry breaking (GSB) perturbations in three-dimensional lattice gauge theories with scalar fields. We study this issue at transitions in which gauge correlations are not critical and the gauge symmetry only selects the ...

Reducible gauge symmetry versus unfree gauge symmetry in Hamiltonian formalism
Nuclear 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.
