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…
Towards the non-perturbative cosmological bootstrap
Matthijs Hogervorst, João Penedones, Kamran Salehi Vaziri
We study quantum field theory on a de Sitter spacetime dS background. Our main tool is the Hilbert space decomposition in irreducible unitary representations of its isometr…
Hamiltonian truncation in Anti-de Sitter spacetime
Matthijs Hogervorst, Marco Meineri, Joao Penedones +1
Quantum Field Theories (QFTs) in Anti-de Sitter (AdS) spacetime are often strongly coupled when the radius of AdS is large, and few methods are available to study them. In this wor…
