Symmetry operators and gravity
SciPost PhysicsWe argue that topological operators for continuous symmetries written in terms of currents need regularization, which effectively gives them a small but finite width. The regulated operator is a finite tension object which fluctuates.

Noether symmetry method for Birkhoffian systems in terms of generalized fractional operators
Theoretical and Applied Mechanics Letters, 2021 Compared with the Hamiltonian mechanics and the Lagrangian mechanics, the Birkhoffian mechanics is more general. The Birkhoffian mechanics is discussed on the basis of the generalized fractional operators, which are proposed recently.

Fluctuation operators and spontaneous symmetry breaking [PDF]
Journal of Mathematical Physics, 2002 We develop an alternative approach to this field, which was to a large extent developed by Verbeure et al. It is meant to complement their approach, which is largely based on a noncommutative central limit theorem and coordinate space estimates. In contrast to that we deal directly with the limits of l-point truncated correlation functions and show ...

Noether Symmetry Method for Hamiltonian Mechanics Involving Generalized Operators
Advances in Mathematical Physics, 2021 Based on the generalized operators, Hamilton equation, Noether symmetry, and perturbation to Noether symmetry are studied. The main contents are divided into four parts, and every part includes two generalized operators.

Complete NNLO operator bases in Higgs effective field theory
Journal of High Energy Physics, 2023 For the first time, we list the complete and independent set of operators at the next-to-next-to-leading order (NNLO) in the Higgs effective field theory (HEFT).

Mixed-symmetry continuous-spin fields in flat and AdS spaces
Physics Letters B, 2021 In the framework of light-cone gauge approach, bosonic and fermionic mixed-symmetry continuous-spin fields in AdS space and flat space are considered. For such fields, the light-cone gauge actions are found.

1-form symmetries of 4d N=2 class S theories
SciPost Physics, 2021 We determine the 1-form symmetry group for any 4d N = 2 class S theory constructed by compactifying a 6d N=(2,0) SCFT on a Riemann surface with arbitrary regular untwisted and twisted punctures.

Mirror symmetry and line operators
Journal of High Energy Physics, 2020 We study half-BPS line operators in 3d N $$ \mathcal{N} $$ = 4 gauge theories, focusing in particular on the algebras of local operators at their junctions.

Colour-twist operators. Part I. Spectrum and wave functions
Journal of High Energy Physics, 2020 We introduce a new class of operators in any theory with a ’t Hooft large-N limit that we call colour-twist operators. They are defined by twisting the colour-trace with a global symmetry transformation and are continuously linked to standard, untwisted ...
