Computing - and -functions from entanglement
Konstantinos Boutivas, Dimitrios Katsinis, Georgios Pastras +1
We confirm the direct connection between entanglement entropy and the notion of irreversibility in the renormalization-group flow in the context of a simple theory for which a calc…
Entanglement on a Sphere
Konstantinos Boutivas, Dimitrios Katsinis, Georgios Pastras +2
We study the entanglement entropy of a massive scalar field in the background of the Einstein universe. We determine numerically the structure of the UV-divergent terms. We study a…
Entanglement Entropy of a Scalar Field in Anti-de Sitter Space
Konstantinos Boutivas, Dimitrios Katsinis, Ioannis Papadimitriou +2
We study the entanglement entropy of a free massive scalar field at its ground state in (3+1)-dimensional AdS space in global coordinates. We consider spherical entangling surfaces…
