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…
Cosmology inside a black hole: adding matter on the brane
José L. F. Barbón, Ayan K. Patra, Juan F. Pedraza +1
Braneworlds inside an AdS black hole provide simple models where a closed cosmology can be encoded in a dual field theory. Previous studies have focused on pure-tension branes, whe…
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…
A Generalized Momentum/Complexity Correspondence
J. L. F. Barbon, J. Martin-Garcia, M. Sasieta
Holographic complexity, in the guise of the Complexity = Volume prescription, comes equipped with a natural correspondence between its rate of growth and the average infall momentu…
Proof of a Momentum/Complexity Correspondence
J. L. F. Barbon, J. Martin-Garcia, M. Sasieta
We show that the holographic Complexity = Volume proposal satisfies a very general notion of Momentum/Complexity correspondence (PC), based on the Momentum Constraint of General Re…
Remarks on the thermodynamic stability of TT-bar deformations
J. L. F. Barbon, E. Rabinovici
We point out that negative specific heat at high energies is a characteristic feature of many TT-bar deformations, both in the original d = 2 case and in d = 1 quantum mechanical c…
