Kasner critical scaling in Einstein--Maxwell--scalar black holes with nonlinear collapse and scalarization
Chihang He, Chao Liu
A critical scaling exponent of was numerically observed for the Kasner parameter of asymptotically flat scalarized black holes and conjectured to be universal [Phys.\ Rev.\ L…

Existence and bounds of nonlinear singularity-free cosmological solutions in a string-inspired gravity
Chihang He, Chao Liu
We provide a rigorous proof for the existence of homogeneous, isotropic and globally singularity-free cosmological solutions in Einstein-dilaton-Gauss-Bonnet (EdGB) gravity with ex…

Proofs on singularity-free solutions and scalarization in nonlinear Einstein-scalar-Gauss-Bonnet cosmology
Chihang He, Chao Liu, Jinhua Wang
The search for singularity-free cosmological solutions has become a highly active topic in the physics community in recent years, yet existing results are largely numerical or base…
