Magnetic charges in supergravity
Journal of High Energy Physics, 2022 In this paper we study the dual charges of N $$ \mathcal{N} $$ = 1 supergravity in asymptotically flat space-time. The action considered is the usual supergravity action with a topological contribution.

Direct observation of nanoscale dynamics of ferroelectric degradation
Nature Communications, 2021 Space charges or injected charges dominate the ferroelectric degradation, however, its physics insight remains unclear. Here, the authors reveal the nature of ferroelectric degradation in nanodevices and the role of the injected charges in polarization ...

Energies, 2019 Many processes are involved in the accumulation of space charges within the insulation materials of high voltage direct current (HVDC) cables, e.g., the local electric field, a conductivity gradient inside the insulation, and the injection of charges at ...

Hydro & thermo dynamics at causal boundaries, examples in 3d gravity
Journal of High Energy Physics, 2023 We study 3-dimensional gravity on a spacetime bounded by a generic 2-dimensional causal surface. We review the solution phase space specified by 4 generic functions over the causal boundary, construct the symplectic form over the solution space and the 4

Commuting charges and symmetric spaces [PDF]
, 2000 Every classical sigma-model with target space a compact symmetric space $G/H$ (with $G$ classical) is shown to possess infinitely many local, commuting, conserved charges which can be written in closed form.

Unification of Spins and Charges in Grassmann Space? [PDF]
, 1994 In a space of d $(d > 5) $ ordinary and d Grassmann coordinates, fields manifest in an ordinary four-dimensional subspace as spinor (1/2, 3/2), scalar, vector or tensor fields with the corresponding charges, according to two kinds of generators of the ...

Space Charge Modulated Electrical Breakdown [PDF]
Scientific Reports, 2016 AbstractElectrical breakdown is one of the most important physical phenomena in electrical and electronic engineering. Since the early 20thcentury, many theories and models of electrical breakdown have been proposed, but the origin of one key issue, that the explanation for dc breakdown strength being twice or higher than ac breakdown strength in ...
