Entanglement and correlations between local observables in de Sitter spacetime
Patricia Ribes-Metidieri, Ivan Agullo, Béatrice Bonga
Studies of quantum field entanglement in de Sitter space based on the von Neumann entropy of local patches have concluded that curvature enhances entanglement between regions and t…

Inflation does not create entanglement in local observables
Patricia Ribes-Metidieri, Ivan Agullo, Béatrice Bonga
Using modern tools of relativistic quantum information, we compare entanglement of a free, massive scalar field in the Bunch-Davies vacuum in the cosmological patch of de Sitter sp…
