de Sitter Entanglement and Conformal Description of the Cosmological Horizon
Felipe Diaz
In this thesis, we aim to understand the microscopic details and origin of the Cosmological Horizon, produced by a static observer in four-dimensional de Sitter (dS) spacetime.…

Liouville description of conical defects in dS, Gibbons-Hawking entropy as modular entropy, and dS holography
Cesar Arias, Felipe Diaz, Rodrigo Olea +1
We model the back-reaction of a static observer in four-dimensional de Sitter spacetime by means of a singular quotient. The set of fixed points of the …

De Sitter Space and Entanglement
Cesar Arias, Felipe Diaz, Per Sundell
We argue that the notion of entanglement in de Sitter space arises naturally from the non-trivial Lorentzian geometry of the spacetime manifold, which consists of two disconnected…
