(Chiral) Virasoro invariance of the tree-level MHV graviton scattering amplitudes
Journal of High Energy Physics, 2022 In this paper we continue our study of the tree level MHV graviton scattering amplitudes from the point of view of celestial holography. In arXiv:2008.04330 we showed that the celestial OPE of two gravitons in the MHV sector can be written as a linear ...

The conformal current algebra on supergroups with applications to the spectrum and integrability [PDF]
, 2010 We compute the algebra of left and right currents for a principal chiral model with arbitrary Wess-Zumino term on supergroups with zero Killing form.

Soft charges and electric-magnetic duality
Journal of High Energy Physics, 2018 The main focus of this work is to study magnetic soft charges of the four dimensional Maxwell theory. Imposing appropriate asymptotic falloff conditions, we compute the electric and magnetic soft charges and their algebra both at spatial and at null ...

Extensions of the asymptotic symmetry algebra of general relativity
Journal of High Energy Physics, 2020 We consider a recently proposed extension of the Bondi-Metzner-Sachs algebra to include arbitrary infinitesimal diffeomorphisms on a 2-sphere. To realize this extended algebra as asymptotic symmetries, we work with an extended class of spacetimes in ...

Diffeomorphisms as quadratic charges in 4d BF theory and related TQFTs
Journal of High Energy Physics, 2023 We present a Sugawara-type construction for boundary charges in 4d BF theory and in a general family of related TQFTs. Starting from the underlying current Lie algebra of boundary symmetries, this gives rise to well-defined quadratic charges forming an ...

Weyl Pair, Current Algebra and Shift Operator [PDF]
, 1994 The Abelian current algebra on the lattice is given from a series of the independent Weyl pairs and the shift operator is constructed by this algebra. So the realization of the operators of the braid group is obtained.

Journal of High Energy Physics, 2021 We construct a Poisson algebra of brane currents from a QP-manifold, and show their Poisson brackets take a universal geometric form. This generalises a result of Alekseev and Strobl on string currents and generalised geometry to include branes with ...

Discrete‐time modelling and stability analysis of wireless power transfer system
IET Power Electronics, 2021 Wireless power transfer (WPT) has been widely used in recent years due to its convenient access to power and security in some specific cases. However, the inherent non‐linearity of the WPT system can result in unexpected stability problems. In this paper,

Deforming soft algebras for gauge theory
Journal of High Energy Physics, 2023 Symmetry algebras deriving from towers of soft theorems can be deformed by a short list of higher-dimension Wilsonian corrections to the effective action.

Nuclear Physics B, 2017 In this paper we study the near horizon symmetry algebra of the non-extremal black hole solutions of the Chern–Simons-like theories of gravity, which are stationary but are not necessarily spherically symmetric.
