The partial Bondi gauge: Gauge fixings and asymptotic charges
SciPost PhysicsIn the companion paper [SciPost Phys. 13, 108 (2022)] we have studied the solution space at null infinity for gravity in the partial Bondi gauge. This partial gauge enables to recover as particular cases and among other choices the Bondi-Sachs and Newman-

Asymptotic Symmetries of Rindler Space at the Horizon and Null Infinity
, 2010 We investigate the asymptotic symmetries of Rindler space at null infinity and at the event horizon using both systematic and ad hoc methods. We find that the approaches that yield infinite-dimensional asymptotic symmetry algebras in the case of anti-de ...

Fields of accelerated sources: Born in de Sitter
, 2005 This paper deals thoroughly with the scalar and electromagnetic fields of uniformly accelerated charges in de Sitter spacetime. It gives details and makes various extensions of our Physical Review Letter from 2002.

Energies, 2019 The air’s partial discharges (PD) under DC voltage are obviously affected by space charges. Discharge pulse parameters have statistical regularity, which can be applied to analyze the space charge effects and discharge characteristics during the ...

Fractional Effective Charges and Misner-Wheeler Charge without Charge Effect in Metamaterials
Photonics, 2016 Transformation optics enables engineering of the effective topology and dimensionality of the optical space in metamaterials. Nonlinear optics of such metamaterials may mimic Kaluza-Klein theories having one or more kinds of effective charges.

Unification of spins and charges in Grassmann space and in space of differential forms [PDF]
, 2000 Polynomials in Grassmann space can be used to describe all the internal degrees of freedom of spinors, scalars and vectors, that is their spins and charges.

, 2007 Molecular orientation fluctuations in ferroelectric smectic liquid crystals produce space charges, due to the divergence of the spontaneous polarization. These space charges interact with mobile ions, so that one must consider the coupled dynamics of the

Asymptotic symmetries of Maxwell theory in arbitrary dimensions at spatial infinity
Journal of High Energy Physics, 2019 The asymptotic symmetry analysis of Maxwell theory at spatial infinity of Minkowski space with d ≥ 3 is performed. We revisit the action principle in de Sitter slicing and make it well-defined by an asymptotic gauge fixing.

Black Holes and (0,4) SCFTs from Type IIB on K3
, 2019 We study the central charges and levels of 2d $\mathcal{N}=(0,4)$ superconformal field theories that are dual to four- and five-dimensional BPS black holes in compactifications of type IIB string theory on a K3 surface.
