Energy extraction from AdS black holes via superradiance
Takaaki Ishii, Youka Kaku, Keiju Murata
Superradiance is known as a wave amplification process caused by rotating or charged black holes. We argue that the superradiance of stationary black holes in asymptotically AdS sp…

Creating stars orbiting in AdS
Youka Kaku, Keiju Murata, Jun Tsujimura
We propose a method to create a star orbiting in an asymptotically AdS spacetime using the AdS/CFT correspondence. We demonstrate that by applying an appropriate source in the quan…

Observing black holes through holographic superconductors
Youka Kaku, Keiju Murata, Jun Tsujimura
We propose a way to observe the photon ring of the asymptotically anti-de Sitter black hole dual to a superconductor on the two-dimensional sphere. We consider the electric current…
