Apparent Horizons Associated with Dynamical Black Hole Entropy
Hideo Furugori, Kanji Nishii, Daisuke Yoshida +1
We define entropic marginally outer trapped surfaces (E-MOTSs) as a generalization of apparent horizons. We then show that, under first-order perturbations around a stationary blac…
Multi-Sheet Wormholes in the Gravitational Soliton Formalism
Yusuke Makita, Keisuke Izumi, Daisuke Yoshida +1
We analytically construct static regular solutions describing wormholes that connect multiple asymptotic regions, supported by a phantom scalar field. The solutions are static and…
Consistency between Bulk and Boundary Causalities in Asymptotically Anti-de Sitter Spacetimes
Lei Fu, Keisuke Izumi, Daisuke Yoshida
We investigate the consistency between bulk and boundary causalities in static, spherically symmetric, asymptotically anti-de Sitter (AdS) spacetimes. We derive a general formula t…
