Irreversibility of quantum field theory in de Sitter: the C, F and A theorems
Nicolás Abate, Nicolás Abate, Gonzalo Torroba
We prove the C, F and A irreversibility theorems in de Sitter spacetime for quantum field theories that are obtained as renormalization group flows from ultraviolet conformal fixed…
Entanglement and Renormalization Group Irreversibility of Quantum Field Theory in AdS
Nicolás Abate, Ignacio Salazar, Gonzalo Torroba
We study nonperturbative aspects of quantum field theory (QFT) in rigid anti de Sitter (AdS) spacetime using quantum information theoretic methods. While irreversibility of renorma…
Exact Mutual Information Difference: Scalar vs. Maxwell Fields
Nicolás Abate, Horacio Casini, Marina Huerta +1
We compute, for any Rényi index , the exact difference between the mutual Rényi informations of a pair of free massless scalars and that of a Maxwell field in dimensions…
Entanglement of a chiral scalar on the torus
Nicolás Abate, David Blanco, Alan Garbarz +2
We compute the entanglement entropy of an interval for a chiral scalar on a circle at an arbitrary temperature. We use the resolvent method, which involves expressing the entropy i…
Quantum information and the C-theorem in de Sitter
Nicolás Abate, Gonzalo Torroba
Information-theoretic methods have led to significant advances in nonperturbative quantum field theory in flat space. In this work, we show that these ideas can be generalized to f…
