Cosmic Inflation From Regular Black Holes
Kensuke Sueto, Riku Yoshimoto, Pablo A. Cano
We study braneworld cosmology in quasi-topological gravity (QTG) with an infinite tower of higher-curvature terms, focusing on the case in which the bulk admits regular black hole…

Motion of a charged test particle around a static black hole in a monopole magnetic field
Ken-ichi Nakao, Yota Endo, Hideki Ishihara +4
We study the motion of a charged test particle in the spacetime with a spherically symmetric black hole which is immersed in a monopole magnetic field. We show that the radial moti…

Classification of global structures of evaporating regular black holes with infinite periods of time
Kensuke Sueto, Hirotaka Yoshino
We carry out model independent analyses for global structures of spherically symmetric regular black holes that evaporate and approach the extremal state spending infinite periods…
