Freezing of Moduli by N=2 Dyons [PDF]

, 1996
In N=2 ungauged supergravity we have found the most general double-extreme dyonic black holes with arbitrary number n_v of constant vector multiplets and n_h of constant hypermultiplets. They are double-extreme: 1) supersymmetric with coinciding horizons,

Gravitational charges of transverse asymptotically AdS spacetimes [PDF]

, 2006
Using Killing-Yano symmetries, we construct conserved charges of spacetimes that asymptotically approach to the flat or Anti-de Sitter spaces only in certain directions.

Stiefel-Whitney topological charges in a three-dimensional acoustic nodal-line crystal

Nature Communications, 2023
Band topology of materials describes the extent Bloch wavefunctions are twisted in momentum space. Such descriptions rely on a set of topological invariants, generally referred to as topological charges, which form a characteristic class in the ...

Charges on Strange Quark Nuggets in Space [PDF]

, 2007
Since Witten's seminal 1984 paper on the subject, searches for evidence of strange quark nuggets (SQNs) have proven unsuccessful. In the absence of experimental evidence ruling out SQNs, the validity of theories introducing mechanisms that increase their

Flat Space Limit of (Higher-Spin) Cardy Formula

, 2015
In this note I derive the flat space limit of the modified Cardy formula associated with inner horizons and show that it reproduces the correct Galilean conformal field theory counting of flat space cosmology microstates.

Space Charge Accumulation in Silicone Rubber Influenced by Poole-Frenkel Effect

MATEC Web of Conferences, 2018
With the rapid increase of electrical energy consumption in metropolises, more and more power cables are utilized in power grid or urban power network to transmit and distribute electrical energy.

Conserved Charges in Even Dimensional Asymptotically locally Anti-de Sitter Space-times

, 2006
Based on the recent paper hep-th/0503045, we derive a formula of calculating conserved charges in even dimensional asymptotically {\it locally} anti-de Sitter space-times by using the definition of Wald and Zoupas.

Source and response soft charges for Maxwell theory on AdS d

Journal of High Energy Physics, 2019
We study asymptotic symmetries and their associated charges for Maxwell theory on anti de Sitter (AdS) background in any dimension. This is obtained by con- structing a conserved symplectic structure for the bulk and a theory on the boundary, which we ...

Black hole entropy and soft hair

Journal of High Energy Physics, 2018
A set of infinitesimal Virasoro L ⊗ Virasoro R diffeomorphisms are presented which act non-trivially on the horizon of a generic Kerr black hole with spin J.
