A note on dual gravitational charges

open access: yesJournal of High Energy Physics, 2020
Dual gravitational charges have been recently computed from the Holst term in tetrad variables using covariant phase space methods. We highlight that they originate from an exact 3-form in the tetrad symplectic potential that has no analogue in metric ...

Unified characterization for higher-order topological phase transitions

open access: yesPhysical Review Research, 2023
Higher-order topological phase transitions (HOTPTs) are associated with closing either the bulk energy gap (type-I) or boundary energy gap (type-II) without changing symmetry, and conventionally, both transitions are captured in real space and ...

D-brane Charges in Five-brane backgrounds [PDF]

open access: yes, 2001
We discuss the discrete Z_k D-brane charges (twisted K-theory charges) in five-brane backgrounds from several different points of view. In particular, we interpret it as a result of a standard Higgs mechanism.

Effect of XLPE/EPDM Interface on Space Charge Behavior in Cable Accessory

open access: yesIEEE Access, 2019
Space charges accumulate easily at insulation interface of cable accessories, which cause different electric field distribution and aging characteristics compared to single-layered cable.

Maximally Symmetric Minimal Unification Model SO(32) with Three Families in Ten Dimensional Space-time

open access: yes, 2007
Based on a maximally symmetric minimal unification hypothesis and a quantum charge-dimension correspondence principle, it is demonstrated that each family of quarks and leptons belongs to the Majorana-Weyl spinor representation of 14-dimensions that ...

Thermodynamics of accelerating AdS $$_4$$ 4 black holes from the covariant phase space

open access: yesEuropean Physical Journal C: Particles and Fields, 2023
We study the charges and first law of thermodynamics for accelerating, non-rotating black holes with dyonic charges in AdS $$_4$$ 4 using the covariant phase space formalism.

Dimensionality of charge space [PDF]

open access: yesIl Nuovo Cimento, 1956
There is no dearth of experimental evidence to indicate that real space-time is a four-dimensional manifold. At present there is much less certainty in attributing dimensions to the charge space of heavy particles, and it may be worth while to review various hypotheses and the meager experimental evidence in this regard. The Clebsch-Gordon coefficients

3d gravity in Bondi-Weyl gauge: charges, corners, and integrability

open access: yesJournal of High Energy Physics, 2021
We introduce a new gauge and solution space for three-dimensional gravity. As its name Bondi-Weyl suggests, it leads to non-trivial Weyl charges, and uses Bondi-like coordinates to allow for an arbitrary cosmological constant and therefore spacetimes ...

On the nonradiating motion of point charges

open access: yes, 2008
We investigate the possible existence of nonradiating motions of systems of point charges, according to classical electrodynamics with retarded potentials. We prove that two point particles of arbitrary electric charges cannot move for an infinitely long
