Cosmological brick walls & quantum chaotic dynamics of de Sitter horizons

Jose M. Begines, Suman Das, Hyun-Sik Jeong, Juan F. Pedraza · 2026

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 holography. In this pa…

On the collimation properties of jets with finite Poynting flux launched from Keplerian accretion discs

Thomas Jannaud, Jonathan Ferreira, Claudio Zanni · 2026

It is generally accepted that the launching of astrophysical jets requires a large-scale magnetic field threading a central object (black hole or star) and/or its surrounding accretion disc. However, …

Holography, Brick Wall and a Little Hierarchy Problem

Vishal Gayari, Chethan Krishnan, Pradipta S. Pathak · 2026

We propose a heuristic for the brick wall in AdS/CFT: the location where a boundary mode's local bulk energy reaches a (Planckian) UV cut-off. This accomplishes two things: (a) the brick wall is frame…
