Krylov complexity and the growth of the black hole interior in 3D gravity
Arpan Bhattacharyya, Sounak Pal, Juan F. Pedraza
We investigate the growth of the black hole interior in three-dimensional gravity from the boundary theory. For the two-sided BTZ black hole, we propose a boundary reconstruction o…
Cosmological brick walls & quantum chaotic dynamics of de Sitter horizons
José M. Begines, Suman Das, Hyun-Sik Jeong +1
Originally proposed by 't Hooft, the brick wall model has recently reemerged as a useful framework for probing quantum aspects of horizon physics, particularly in the context of ho…
Lorentzian threads and nonlocal computation in holography
Elena Cáceres, Rafael Carrasco, Juan F. Pedraza
Recent advances in holography and quantum gravity have shown that CFTs with classical gravity duals can implement nonlocal quantum computation protocols that appear local from the…
Quantum censors: backreaction builds horizons
Antonia M. Frassino, Robie A. Hennigar, Juan F. Pedraza +1
Cosmic censorship posits spacetime singularities remain concealed behind event horizons, preserving the determinism of General Relativity. While quantum gravity is expected to reso…
The landscape of complexity measures in 2D gravity
Elena Cáceres, Rafael Carrasco, Vaishnavi Patil +2
We investigate the broad landscape of holographic complexity measures for theories dual to two-dimensional (2D) dilaton gravity. Previous studies have largely focused on the comple…
Quantum induced superradiance
Casey Cartwright, Umut Gürsoy, Juan F. Pedraza +1
Superradiance, the phenomenon enabling energy extraction through radiation amplification, is not universal to all black holes. We show that semi-classical backreaction can induce s…
