Curvature driven diffusion, Rayleigh-Plateau, and Gregory-Laflamme
Umpei Miyamoto
It can be expected that the respective endpoints of the Gregory-Laflamme black brane instability and the Rayleigh-Plateau membrane instability are related because the bifurcation d…
Hidden symmetries, null geodesics, and photon capture in the Sen black hole
Kenta Hioki, Umpei Miyamoto
Important classes of null geodesics and hidden symmetries in the Sen black hole are investigated. First, we obtain the principal null geodesics and circular photon orbits. Then, an…
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…
Analytic evidence for the Gubser-Mitra conjecture
Umpei Miyamoto
A simple master equation for the static perturbation of charged black strings is derived while employing the gauge proposed by Kol. As the charge is varied it is found that the pot…
Generic features of Einstein-Aether black holes
Takashi Tamaki, Umpei Miyamoto
We reconsider spherically symmetric black hole solutions in Einstein-Aether theory with the condition that this theory has identical PPN parameters as those for general relativity,…
