Supergravity flows, wormholes and their pseudo-Hermitian holographic duals
Jose M. Begines, Antón F. Faedo, Carlos Hoyos +1
We find solutions to consistent truncations of supergravity where some real scalars are analytically extended to imaginary values, ensuring the metric remains real-valued. Among th…

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…
