Gyromagnetic Ratio of Charged Kerr-Anti-de Sitter Black Holes [PDF]

, 2006
We examine the gyromagnetic ratios of rotating and charged AdS black holes in four and higher spacetime dimensions. We compute the gyromagnetic ratio for Kerr-AdS black holes with an arbitrary electric charge in four dimensions and show that it ...

Large Transverse Thermoelectric Effect in Weyl Semimetal TaIrTe4 Engineered for Photodetection

Advanced Functional Materials, EarlyView.
This experimental work shows that the anomalous scanning photocurrent response patterns of the Weyl semimetal TaIrTe4${\rm TaIrTe}_4$ under visible and long‐wave infrared illumination are due to a large transverse thermoelectric response of the material.

Rotating extremal black holes in Einstein-Born-Infeld theory

Journal of High Energy Physics
We construct exact solutions that describe the near horizon region of extremal rotating black holes in Einstein-Born-Infeld theory. Using generalized Komar integrals, we extract the electric charge and angular momentum from the near horizon geometries ...

Thin accretion disks and charged rotating dilaton black holes

European Physical Journal C: Particles and Fields, 2020
Einstein-Maxwell-dilaton theory is an interesting theory of gravity for studying scalar fields in the context of no-hair theorem. In this work, we consider static charged dilaton and charged, slowly rotating dilaton black holes in Einstein-Maxwell ...

Can accretion disk properties distinguish gravastars from black holes? [PDF]

, 2009
Gravastars, hypothetic astrophysical objects, consisting of a dark energy condensate surrounded by a strongly correlated thin shell of anisotropic matter, have been proposed as an alternative to the standard black hole picture of general relativity ...

Asymptotic spectroscopy of rotating black holes [PDF]

Physical Review D, 2008
We calculate analytically the transmission and reflection amplitudes for waves incident on a rotating black hole in d=4, analytically continued to asymptotically large, nearly imaginary frequency. These amplitudes determine the asymptotic resonant frequencies of the black hole, including quasinormal modes, total-transmission modes and total-reflection ...

Artificial Intelligence‐Assisted Workflow for Transmission Electron Microscopy: From Data Analysis Automation to Materials Knowledge Unveiling

Advanced Materials, EarlyView.
AI‐Assisted Workflow for (Scanning) Transmission Electron Microscopy: From Data Analysis Automation to Materials Knowledge Unveiling. Abstract (Scanning) transmission electron microscopy ((S)TEM) has significantly advanced materials science but faces challenges in correlating precise atomic structure information with the functional properties of ...

Universal thermodynamic topological classes of three-dimensional BTZ black holes

Physics Letters B
We establish a universal thermodynamic topological classification for three-dimensional static neutral Bañados-Teitelboim-Zanelli (BTZ), charged BTZ, and rotating BTZ black holes.

Gluing gravitational blocks for AdS black holes

Journal of High Energy Physics, 2019
We provide a unifying entropy functional and an extremization principle for black holes and black strings in AdS4 × S 7 and AdS5 × S 5 with arbitrary rotation and generic electric and magnetic charges.

Large rotating AdS black holes from fluid mechanics

, 2008
We use the AdS/CFT correspondence to argue that large rotating black holes in global AdS(D) spaces are dual to stationary solutions of the relativistic Navier-Stokes equations on S**(D-2).
