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…

Solving formally the Auxiliary System of $O (N)$ Non Linear Sigma Model

Dimitrios Katsinis

We show that the integrability of the $S O (N) / S O (N - 1)$ Principal Chiral Model (PCM) originates from the Pohlmeyer reduction of the $O (N)$ Non Linear Sigma Model (NLSM). In particula…
