Holographic Entropy and Calabi's Diastasis [PDF]
, 2014 The entanglement entropy for interfaces and junctions of two-dimensional CFTs is evaluated on holographically dual half-BPS solutions to six-dimensional Type 4b supergravity with m anti-symmetric tensor supermultiplets.

Symmetries at causal boundaries in 2D and 3D gravity
Journal of High Energy Physics, 2022 We study 2d and 3d gravity theories on spacetimes with causal (timelike or null) codimension one boundaries while allowing for variations in the position of the boundary.

Soft charges from the geometry of field space
Journal of High Energy Physics, 2020 Infinite sets of asymptotic soft-charges were recently shown to be related to new symmetries of the S-matrix, spurring a large amount of research on this and related questions.

Higher-spin flat space cosmologies with soft hair
Journal of High Energy Physics, 2017 We present and discuss near horizon boundary conditions for flat space higher-spin gravity in three dimensions. As in related work our boundary conditions ensure regularity of the solutions independently of the charges. The asymptotic symmetry algebra is

Null boundary phase space: slicings, news & memory
Journal of High Energy Physics, 2021 We construct the boundary phase space in D-dimensional Einstein gravity with a generic given co-dimension one null surface N $$ \mathcal{N} $$ as the boundary.

Depletion Layers and Domain Walls in Semiconducting Ferroelectric Thin Films [PDF]
, 2005 Commonly used ferroelectric perovskites are also wide-band-gap semiconductors. In such materials, the polarization and the space-charge distribution are intimately coupled, and this Letter studies them simultaneously with no a priori ansatz on either. In

, 2014 The space charge forces are those generated directly by the charge distribution, with the inclusion of the image charges and currents due to the interaction of the beam with a perfectly conducting smooth pipe. Space charge forces are responsible for several unwanted phenomena related to beam dynamics, such as energy loss, shift of the synchronous phase

Dyon production from near-extremal Kerr–Newman–(anti-)de Sitter black holes
European Physical Journal C: Particles and Fields, 2023 Using the enhanced symmetry in the near-horizon region of the near-extremal dyonic Kerr–Newman (KN) black hole in the (A)dS space, we find the exact solutions for dyonic charged scalar field in terms of the hypergeometric function and explicitly compute ...

Electric Model for Electromagnetic Wave Fields
IEEE Access, 2021 This paper presents the first theoretical framework that defines the electric infinitesimal structure model of electromagnetic waves. This model represents the electromagnetic fields by electric field components only.
