AdS Black Holes Are Short-Lived inside the Spectral Form Factor
José L. F. Barbón, Eduardo Velasco-Aja
We analyze the contribution of AdS black hole saddles to the spectral form factor of -dimensional CFTs with a gravity dual. At high temperatures, the analytically continued grav…

A Note on Black Hole Entropy and Wormhole Instabilities
J. L. F. Barbon, E. Velasco-Aja
We discuss recent approaches to the computation of black hole entropies through semiclassical estimates of appropriate state overlaps, saturated by Euclidean wormhole configuration…

Quantum corrections to Einstein's equations
Eduardo Velasco-Aja, Jesus Anero
In this master thesis, the Frobenius power series method is used to find spherically symmetric and static vacuum solutions to quadratic and cubic gravitational actions, representin…
