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…

Spectrum of BPS black holes in $A d S_{3} \times S^{3} \times S^{3} \times S^{1}$

Matthew Heydeman, Xiaoyi Shi, Gustavo J. Turiaci

We uncover novel features in the spectrum of BPS and near-BPS states in asymptotically $A d S_{3} \times S^{3} \times S^{3} \times S^{1}$ spacetimes. This follows from a careful analysis of…

Can black holes preserve $N > 4$ supersymmetry?

Matthew Heydeman, Xiaoyi Shi, Gustavo J. Turiaci

The dynamics of near-BPS black holes are governed by the breaking of the conformal symmetry that emerges near their horizons. Using the classification of superconformal symmetries,…

The phase of the gravitational path integral

Xiaoyi Shi, Gustavo J. Turiaci

The gravitational path integral on $S^{2} \times S^{2}$ can be interpreted either as evaluating a contribution to the norm of the Hartle-Hawking wavefunction conditional on spatial $S^…
