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…
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…
Hawking radiation of a vector field and gravitational anomalies
Keiju Murata, Umpei Miyamoto
Recently, the relation between Hawking radiation and gravitational anomalies has been used to estimate the flux of Hawking radiation for a large class of black objects. In this pap…
High and Low Dimensions in The Black Hole Negative Mode
Vadim Asnin, Dan Gorbonos, Shahar Hadar +3
The negative mode of the Schwarzschild black hole is central to Euclidean quantum gravity around hot flat space and for the Gregory-Laflamme black string instability. We analyze th…
On Hawking radiation from black rings
Umpei Miyamoto, Keiju Murata
We calculate the quantum radiation from the five dimensional charged rotating black rings by demanding the radiation to eliminate the possible anomalies on the horizons. It is show…
