Trace Anomalies and the Graviton-Dilaton Amplitude
Denis Karateev, Zohar Komargodski, João Penedones +1
We consider 3+1 dimensional Quantum Field Theories (QFTs) coupled to the dilaton and the graviton. We show that the graviton-dilaton scattering amplitude receives a universal contr…
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 th…
Renormalization group flows in AdS and the bootstrap program
Marco Meineri, Joao Penedones, Taro Spirig
We study correlation functions of the bulk stress tensor and boundary operators in Quantum Field Theories (QFT) in Anti-de Sitter (AdS) space. In particular, we derive new sum rule…
Numerical tests of the large charge expansion
Gabriel Cuomo, J. M. Viana Parente Lopes, José Matos +2
We perform Monte-Carlo measurements of two and three point functions of charged operators in the critical O(2) model in 3 dimensions. Our results are compatible with the prediction…
Hilbert space of Quantum Field Theory in de Sitter spacetime
Joao Penedones, Kamran Salehi Vaziri, Zimo Sun
We study the decomposition of the Hilbert space of quantum field theory in dimensional de Sitter spacetime into Unitary Irreducible Representations (UIRs) of its isometry g…
