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…
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…
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…
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…
