Black hole-black string phase transitions from hydrodynamics
Kei-ichi Maeda, Umpei Miyamoto
We discuss the phase transitions between three states of a plasma fluid (plasma ball, uniform plasma tube, and non-uniform plasma tube), which are dual to the corresponding finite…
Black hole entropy for the general area spectrum
Tomo Tanaka, Takashi Tamaki
We consider the possibility that the horizon area is expressed by the general area spectrum in loop quantum gravity and calculate the black hole entropy by counting the degrees of…
UV caps, IR modification of gravity, and recovery of 4D gravity in regularized braneworlds
Tsutomu Kobayashi
In the context of six-dimensional conical braneworlds we consider a simple and explicit model that incorporates long distance modification of gravity and regularization of codimens…
Liquid bridges and black strings in higher dimensions
Umpei Miyamoto, Kei-ichi Maeda
Analyzing a capillary minimizing problem for a higher-dimensional extended fluid, we find that there exist startling similarities between the black hole-black string system (the Gr…
Quasinormal modes of black holes localized on the Randall-Sundrum 2-brane
Masato Nozawa, Tsutomu Kobayashi
We investigate conformal scalar, electromagnetic, and massless Dirac quasinormal modes of a brane-localized black hole. The background solution is the four-dimensional black hole o…
Curvature corrections to the low energy effective theory in 6D regularized braneworlds
Tsutomu Kobayashi, Tetsuya Shiromizu, Claudia de Rham
We study the effective gravitational theory on a brane in a six-dimensional Einstein-Maxwell model of flux compactification, regularizing a conical defect as a codimension-one bran…
