On the Entanglement Entropy of Quantum Fields in Causal Sets
Alessio Belenchia, Dionigi M. T. Benincasa, Marco Letizia +1
In order to understand the detailed mechanism by which a fundamental discreteness can provide a finite entanglement entropy, we consider the entanglement entropy of two classes of…

Transmission of Information in Non-Local Field Theories
Alessio Belenchia, Dionigi M. T. Benincasa, Stefano Liberati +1
The signaling between two observers in 3+1 dimensional flat spacetime coupled locally to a non-local field is considered. We show that in the case where two observers are purely ti…
