Asymptotic symmetries of Yang-Mills fields in Hamiltonian formulation
Journal of High Energy Physics, 2020 We investigate the asymptotic symmetry group of the free SU(N )-Yang-Mills theory using the Hamiltonian formalism. We closely follow the strategy of Henneaux and Troessaert who successfully applied the Hamiltonian formalism to the case of gravity and ...

Carrollian and Galilean conformal higher-spin algebras in any dimensions
Journal of High Energy Physics, 2022 We present higher-spin algebras containing a Poincaré subalgebra and with the same set of generators as the Lie algebras that are relevant to Vasiliev’s equations in any space-time dimension D ≥ 3. Given these properties, they can be considered either as

Non-Lorentzian theories with and without constraints
Journal of High Energy Physics, 2023 We exhibit a new method of constructing non-Lorentzian models by applying a method we refer to as starting from a so-called seed Lagrangian. This method typically produces additional constraints in the system that can drastically alter the physical ...

On the Embedding of Space-Time Symmetries into Simple Superalgebras [PDF]
, 2001 We explore the embedding of Spin groups of arbitrary dimension and signature into simple superalgebras in the case of extended supersymmetry. The R-symmetry, which generically is not compact, can be chosen compact for all the cases that are congruent mod

COLORED SYMMETRIES IN SPACE–TIME
Computers & Mathematics with Applications, 1986 AbstractThe paper displays a single objective: to show the emergence of symmetries as a universal, archetypal, self-organizing phenomenon which originates in an infinite number of forms all having the same trihedral innate structure. These forms have been generated by the use of a single-type, right-handed element containing three spatial dimensions ...

Time after time – circadian clocks through the lens of oscillator theory
FEBS Letters, EarlyView.Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.

Irreducible representations of the Poincaré group with reflections and two-fold Wigner degeneracy
Journal of High Energy PhysicsNot all complete set of spinors can be used as expansion coefficients of a quantum field. In fact, Steven Weinberg established the uniqueness of Dirac spinors for this purpose provided: (a) one paid due attention to the multiplicative phases for each of ...

Hamiltonian structure and asymptotic symmetries of the Einstein-Maxwell system at spatial infinity
Journal of High Energy Physics, 2018 We present a new set of asymptotic conditions for gravity at spatial infinity that includes gravitational magnetic-type solutions, allows for a non-trivial Hamiltonian action of the complete BM S 4 algebra, and leads to a non-divergent behaviour of the ...

Gauss’ Law and string-localized quantum field theory
Journal of High Energy Physics, 2020 The quantum Gauss Law as an interacting field equation is a prominent feature of QED with eminent impact on its algebraic and superselection structure. It forces charged particles to be accompanied by “photon clouds” that cannot be realized in the Fock ...
