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…
Bounds on multiscalar CFTs in the epsilon expansion
Matthijs Hogervorst, Chiara Toldo
We study fixed points with N scalar fields in dimensions to leading order in using a bottom-up approach. We do so by analyzing O(N) invariants of th…
RG flows on and Hamiltonian truncation
Matthijs Hogervorst
We describe a nonperturbative method to compute the partition function and correlation functions for scalar QFTs set on the -dimensional sphere . The method relies on a Ham…
Crossing Kernels for Boundary and Crosscap CFTs
Matthijs Hogervorst
This paper investigates d-dimensional CFTs in the presence of a codimension-one boundary and CFTs defined on real projective space RP^d. Our analysis expands on the alpha space met…
Crossing Symmetry in Alpha Space
Matthijs Hogervorst, Balt C. van Rees
We initiate the study of the conformal bootstrap using Sturm-Liouville theory, specializing to four-point functions in one-dimensional CFTs. We do so by decomposing conformal corre…
