Nonperturbative Mellin Amplitudes: Existence, Properties, Applications
Joao Penedones, Joao A. Silva, Alexander Zhiboedov
We argue that nonperturbative CFT correlation functions admit a Mellin amplitude representation. Perturbative Mellin representation readily follows. We discuss the main properties…
Bootstrapping Massive Quantum Field Theories
Denis Karateev, Simon Kuhn, Joao Penedones
We propose a new non-perturbative method for studying UV complete unitary quantum field theories (QFTs) with a mass gap in general number of spacetime dimensions. The method relies…
Flux Tube S-matrix Bootstrap
Joan Elias Miro, Andrea L. Guerrieri, Aditya Hebbar +2
We bootstrap the S-matrix of massless particles in unitary, relativistic two dimensional quantum field theories. We find that the low energy expansion of such S-matrices is strongl…
The S-matrix Bootstrap IV: Multiple Amplitudes
Alexandre Homrich, Joao Penedones, Jonathan Toledo +2
We explore the space of consistent three-particle couplings in -symmetric two-dimensional QFTs using two first-principles approaches. Our first approach relies solely…
Colliders and conformal interfaces
Marco Meineri, Joao Penedones, Antonin Rousset
We set up a scattering experiment of matter against an impurity which separates two generic one-dimensional critical quantum systems. We compute the flux of reflected and transmitt…
