Title:

Bootstrap meets experiments: from formal constraints to real-world predictions

Abstract:

The numerical bootstrap is a non-perturbative approach for studying strongly coupled CFTs and QFTs. It transforms formal constraints -- such as unitarity and crossing symmetry -- into predictions for physical observables in both condensed matter and particle physics. In this talk, I will review recent groundbreaking developments in the numerical bootstrap. For the condensed matter applications, I will show how this approach produces remarkable insights into real-world phenomena, from critical transitions in Helium-4 superfluidity and perovskite materials to deconfined quantum criticality. For the particle physics applications, I will use S-matrix bootstrap to predict the existence of an isospin-2 meson at 2 GeV, a previously unknown particle. I will also discuss future directions for broader application of numerical bootstrap in physics.
