Matter Maps to Geometry in Gravitational Collapse
H. Khodabakhshi, Zhi-Chao Li, H. Lu +1
We establish an exact bidirectional map between the effective homogeneous interior density of a collapsing star and the exterior metric function in generalized Oppenheimer--Snyder…
Lorentz-Violating (Regular) Black Holes in Einstein Gravity
Zhi-Chao Li, H. Lu
We introduce a minimally coupled dark sector based on a nonlinear electrodynamics to generate regular spacetime textures that interpolate from a regular core to an asymptotic Loren…
Kasner Singularity of Black Holes in Einstein-scalar Gravity
Ze-Xuan Xiong, H. Lu
We study the spacelike Kasner singularity of spherically-symmetric, static and asymptotically flat black holes in Einstein gravity minimally coupled to a massless scalar with a sui…
Desclarizing the Wormhole to Black Hole with Negative Mass
Ze Li, Hai-Shan Liu, H. Lu
We construct new black holes using the curvature-induced scalarization mechanism in Einstein gravity coupled to a massless phantom scalar. We find that the general wormhole solutio…
