Quantum fate of the Choptuik naked singularity
Chih-Hung Wu
Classical critical collapse provides a dynamical route from smooth initial data to a naked singularity, representing a sharper violation of predictability than ordinary black hole…

The Fate of Nucleated Black Holes in de Sitter Quantum Gravity
Xiaoyi Shi, Gustavo J. Turiaci, Chih-Hung Wu
The Euclidean Nariai geometry has long been proposed as the instanton describing the nucleation of maximal-mass black holes in de Sitter space. We place this interpretation on firm…

The wavefunction of a quantum universe
Gustavo J. Turiaci, Chih-Hung Wu
We study quantum gravity corrections to the no-boundary wavefunction describing a universe with spatial topology . It has been suggested that quantum effects become…
