Entanglement Entropy as a Probe Beyond the Horizon
Konstantinos Boutivas, Dimitrios Katsinis, Georgios Pastras +1
The entanglement entropy of a free field in de Sitter space is enhanced by the squeezing of its modes. We show analytically that the expansion induces a term in the entanglement en…

A Numerical Calculation of Entanglement Entropy in de Sitter Space
Konstantinos Boutivas, Dimitrios Katsinis, Georgios Pastras +1
The entanglement entropy of a massless scalar field in de Sitter space depends on multiple scales, such as the radius of the entangling surface, the Hubble constant and the UV cuto…
