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…
3D Gravity and Chaos in CFTs with Fermions
Jan Boruch, Elisa Tabor, Gustavo J. Turiaci
Pure 3d gravity in AdS is believed to admit a holographic description in terms of 2d CFT. We introduce a theory of fermionic 3d gravity where we sum over geometries equipped with s…
Spectrum of BPS black holes in
Matthew Heydeman, Xiaoyi Shi, Gustavo J. Turiaci
We uncover novel features in the spectrum of BPS and near-BPS states in asymptotically spacetimes. This follows from a careful analysis of…
Can black holes preserve 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 can be interpreted either as evaluating a contribution to the norm of the Hartle-Hawking wavefunction conditional on spatial $S^…
Les Houches lectures on two-dimensional gravity and holography
Gustavo J. Turiaci
Lecture notes prepared for the Les Houches school "Quantum Geometry: Mathematical Methods for Gravity, Gauge Theories and Non-Perturbative Physics" that took place during the summe…
