Black holes in the gravity/gauge theory correspondence [PDF]

, 2002
The AdS/CFT correspondence provides a microscopic description of black hole thermodynamics. In this thesis, I study the relation between the classical physics of black holes and this microscopic description.

Non-spinning tops are stable

Journal of High Energy Physics
We consider coupled gravitational and electromagnetic perturbations of a family of five-dimensional Einstein-Maxwell solutions that describes both magnetized black strings and horizonless topological stars.

Black hole thermodynamics with dynamical lambda

Journal of High Energy Physics, 2017
We study evolution and thermodynamics of a slow-roll transition between early and late time de Sitter phases, both in the homogeneous case and in the presence of a black hole, in a scalar field model with a generic potential having both a maximum and a ...

Massive vector fields in Kerr-Newman and Kerr-Sen black hole spacetimes

Journal of High Energy Physics, 2020
The superradiant instability modes of ultralight massive vector bosons are studied for weakly charged rotating black holes in Einstein-Maxwell gravity (the Kerr- Newman solution) and low-energy heterotic string theory (the Kerr-Sen black hole).

Influence of Moisture on Electrical Properties of Fibre‐Reinforced Polymer Core Rod in the Decay‐Like Degraded Composite Insulator

High Voltage, EarlyView.
ABSTRACT Abnormal heating due to decay‐like degradation in composite insulators is influenced by environmental moisture, but the relationship between the internal degradation status of the core rods and their electrical properties under varying humidity conditions remains poorly understood. In this work, the decay‐like degraded fibre‐reinforced polymer

Massless black holes and conifolds in string theory [PDF]

, 1995
Low-energy effective field theories arising from Calabi-Yau string compactifications are generically inconsistent or ill-defined at the classical level because of conifold singularities in the moduli space.

Braneworld black holes and black strings [PDF]

, 2008
This thesis involves the study of strong and weak gravity phenomenology within the braneworld paradigm. We begin with a general overview of the hypothesised concept of extra spatial dimensions and explain why they are so interesting.

Brickwall in rotating BTZ: a dip-ramp-plateau story

Journal of High Energy Physics
In this article, building on our recent investigations and motivated by the fuzzball-paradigm, we explore normal modes of a probe massless scalar field in the rotating BTZ-geometry in an asymptotically AdS spacetime and correspondingly obtain the ...

Research on Self‐Identification Technology of Zero‐Value Insulators in Distribution Lines Based on Electroluminescence Effect

High Voltage, EarlyView.
ABSTRACT To address the issue of low detection accuracy for zero‐value insulators in distribution lines, this study proposes a novel method for detecting these insulators based on the electroluminescence effect. Through theoretical analysis and experimentation, it was found that the luminescence intensity of ZnS:Cu electroluminescent material varies ...
