Detector operators for celestial symmetries
Journal of High Energy Physics, 2023 Abstract This paper presents a systematic cataloging of the generators of celestial symmetries on phase space. Starting from the celestial OPEs, we first show how to extract a representation of the general-spin analog of the wedge subalgebra of w1+∞ on the phase space of massless matter fields of arbitrary helicity.

Symmetry of Open Quantum Systems: Classification of Dissipative Quantum Chaos
PRX Quantum, 2023 We develop a theory of symmetry in open quantum systems. Using the operator-state mapping, we characterize symmetry of Liouvillian superoperators for the open quantum dynamics by symmetry of operators in the double Hilbert space and apply the 38-fold ...

Symmetry and Intertwining Operators for the Nonlocal Gross-Pitaevskii Equation
Symmetry, Integrability and Geometry: Methods and Applications, 2013 We consider the symmetry properties of an integro-differential multidimensional Gross-Pitaevskii equation with a nonlocal nonlinear (cubic) term in the context of symmetry analysis using the formalism of semiclassical asymptotics.

On continuous 2-category symmetries and Yang-Mills theory
Journal of High Energy Physics, 2022 We study a 4d gauge theory U(1) N−1 ⋊ S N obtained from a U(1) N−1 theory by gauging a 0-form symmetry S N . We show that this theory has a global continuous 2-category symmetry, whose structure is particularly rich for N > 2.

SOS: symmetry-operational similarity [PDF]
npj Quantum Materials, 2019 AbstractSymmetry often governs condensed matter physics. The act of breaking symmetry spontaneously leads to phase transitions, and various observables or observable physical phenomena can be directly associated with broken symmetries. Examples include ferroelectric polarization, ferromagnetic magnetization, optical activities (including Faraday and ...

Mirror symmetry and loop operators [PDF]
Journal of High Energy Physics, 2015 Wilson loops in gauge theories pose a fundamental challenge for dualities. Wilson loops are labeled by a representation of the gauge group and should map under duality to loop operators labeled by the same data, yet generically, dual theories have completely different gauge groups.

Generalized charges, part I: Invertible symmetries and higher representations
SciPost Physics$q$-charges describe the possible actions of a generalized symmetry on $q$-dimensional operators. In Part I of this series of papers, we describe $q$-charges for invertible symmetries; while the discussion of $q$-charges for non-invertible symmetries is ...

Effective operators and extended symmetry [PDF]
Nuclear Physics B, 1994 In this note we expand on our previous study of the implications of LEP1 results for future colliders. We extend the effective operator-based analysis of De R jula et al. to a larger symmetry group, and show at which cost their expectations can be relaxed.

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.
