The Globally Trapped Future: A Fate for Black Holes and Wormholes
Yi-bo Liang, Hong-Rong Li
We demonstrate, for the first time, that arbitrary spherically symmetric metrics can be derived within a framework based on the coupling of two scalar fields and an electromagnetic…

Regular Power-Maxwell Black Holes
Yi-bo Liang, Hong-Rong Li
We present a new class of regular, spherically symmetric spacetimes in nonlinear electrodynamics that are asymptotically dynamical but not de Sitter, exhibiting power-law Maxwell b…
