QFT as a set of ODEs: higher dimensions
Fabiana De Cesare, Manuel Loparco
Correlation functions of local operators in Quantum Field Theory (QFT) in Anti-de Sitter space (AdS) are completely fixed by the QFT data: the set of scaling dimensions and O…
RG flows in de Sitter: c-functions and sum rules
Manuel Loparco
We study the renormalization group flow of unitary Quantum Field Theories on two-dimensional de Sitter (dS) spacetime. We prove the existence of two functions of the radius of dS t…
QFT as a set of ODEs
Manuel Loparco, Grégoire Mathys, Joao Penedones +2
Correlation functions of local operators in Quantum Field Theory (QFT) on hyperbolic space can be fully characterized by the set of QFT data $\lbrace Î_i,C_{ijk},b^{\hat{\mathcal{…
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…
The Källén-Lehmann representation in de Sitter spacetime
Manuel Loparco, Joao Penedones, Kamran Salehi Vaziri +1
We study two-point functions of symmetric traceless local operators in the bulk of de Sitter spacetime. We derive the Källén-Lehmann spectral decomposition for any spin and show…
