Hairy black holes and the endpoint of AdS$_4$ charged superradiance
, 2017 We construct hairy black hole solutions that merge with the anti-de Sitter (AdS$_4$) Reissner-Nordstr\"om black hole at the onset of superradiance. These hairy black holes have, for a given mass and charge, higher entropy than the corresponding AdS$_4 ...

Advanced Functional Materials, EarlyView.This work reports the self‐assembly of a pyrene derivative into two distinct nanostructures and their application in visible‐light photocatalysis. The two nanostructures exhibit completely different yet complementary photocatalytic activities, promoting either H2 or H2O2 evolution.

Photon Shells, Black Hole Shadows, and Accretion Toroids
The Astrophysical Journal Supplement SeriesWe analyze the properties of the Kerr black hole (BH) photon shell, focusing on the influence of aggregates of corotating and counterrotating toroids (ringed accretion disks, hereafter RAD), orbiting in the BH photon shell (photon shell “obscuration ...

Advanced Functional Materials, EarlyView.The versatile precursor‐assisted soft sphere close packing during slot‐die coating is investigated with in situ X‐ray scattering. The soft crystallization pathways towards a close packing involve multistep structural transitions such as surface nucleation, in‐plane, and out‐of‐plane crystallization.

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).

Advanced Functional Materials, EarlyView.The chemical composition and band alignment are systematically investigated at the TiO2/InP heterointerface. Thin TiO2 films are deposited by ALD on atomically ordered, P‐terminated p‐InP(100). By combining UPS, XPS, and ab initio molecular dynamics, the atomistic structure and electronic alignment are revealed.

Strong gravitational lensing effects around rotating regular black holes
Physics Letters BIn this letter, we investigate the strong gravitational lensing effects around two classes of rotating regular black holes, which behave as non-singular Minkowski core at the center.

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.

Non-asymptotically flat, non-AdS dilaton black holes
, 2004 We show that previously known non-asymptotically flat static black hole solutions of Einstein-Maxwell-dilaton theory may be obtained as near-horizon limits of asymptotically flat black holes.
