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…

Irreversibility of quantum field theory in de Sitter: the C, F and A theorems
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…

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…
