Locality constraints in AdS without parity
Manuel Loparco, Grégoire Mathys, João Penedones +2
We study bulk locality constraints in quantum field theories in AdS. The known derivation of locality sum rules in AdS does not apply for due to the different sin…

What is a photon in de Sitter spacetime?
Manuel Loparco, Joao Penedones, Yannis Ulrich
The states of a single photon in four-dimensional de Sitter (dS) spacetime form a Unitary Irreducible Representation (UIR) of SO(1,4), which we call the photon UIR. While in flat s…
