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 $S^{1} \times S^{2}$ universe

Gustavo J. Turiaci, Chih-Hung Wu

We study quantum gravity corrections to the no-boundary wavefunction describing a universe with spatial topology $S^{1} \times S^{2}$ . It has been suggested that quantum effects become…
