de Sitter holography from a Lorentzian torus
Kosei Fujiki, Michitaka Kohara, Javier Moreno +2
We show that the quantum entanglement between the conformal field theories (CFTs) living on the future and past boundaries in the de Sitter/conformal field theory (dS/CFT) correspo…
Universality of pseudoentropy for deformed spheres in dS/CFT
Giorgos Anastasiou, Ignacio J. Araya, Avijit Das +1
We determine the universal part of pseudoentropy for small shape deformations of spherical entangling surfaces in the context of de Sitter/conformal field theory (dS/CFT) correspon…
Renormalized pseudoentropy in dS/CFT
Giorgos Anastasiou, Ignacio J. Araya, Avijit Das +1
We study holographic pseudoentropy for subregions in non-unitary Euclidean conformal field theories (CFTs) within the framework of the de Sitter/conformal field theory (dS/CFT) cor…
Cosmological higher-curvature gravities
Javier Moreno, Ãngel J. Murcia
We examine higher-curvature gravities whose FLRW configurations are specified by equations of motion which are of second order in derivatives, just like in Einstein gravity. We nam…
Holographic explorations of regular black holes in pure gravity
Monserrat Aguayo, Leonardo Gajardo, Nicolás Grandi +3
It has been recently established in \textit{Phys.Lett.B 861 (2025) 139260} that regular, asymptotically flat black holes exist in pure gravity theories in dimension greater than fo…
