The Bootstrap workshop is the annual meeting of the bootstrap collaboration . The meeting is intended to update all members of the collaboration about the most significant achievements obtained during the year, foster discussions, and provide a genuine co-working environment among all the participants. The daily agenda is structured as follows. Mornings: Research talks and mini course lectures. Afternoons: Discussion sessions. Collaboration time. Informal and spontaneously organized presentations. More discussions.

When, how and why of the bootstrap collaboration? Understanding the basic building blocks of Nature has led to the discovery of Quantum Field Theory (QFT), a universal language for theoretical physics that describes the Standard Model of particle physics, early universe inflation, and condensed matter phenomena such as phase transitions, superconductors, and quantum Hall fluids. A triumph of 20th century was to understand weakly coupled QFTs, and perturbative methods have indeed led to a number of verified experimental predictions. However, a deeper understanding of Nature at all scales requires a comprehensive understanding of strongly coupled emergent phenomena, from the strong nuclear force to high temperature superconductivity, and this has remained a hard problem to solve, especially with traditional methods. In recent years, new techniques have challenged this difficulty by showing that an optimized knowledge of symmetries and consistency conditions actually leads to unprecedented quantitative results. The starting point is the astonishing discovery that the space of QFTs can be determined by using only general principles: symmetries and quantum mechanics. By analyzing the full implications of these general principles, one can make sharp predictions for physical observables without resorting to approximations. This strategy is called the bootstrap. The critical challenge for the 21st century is to map and understand the whole space of QFTs, including strongly coupled models, and this is the main goal of the Simons Collaboration on the Nonperturbative Bootstrap.
