This edition of the Bootstrap will take place at the Instituto Principia in São Paulo, Brazil, from June 26 to July 14 of 2023.

Quantum field theory (QFT) is a universal language for theoretical physics, describing the Standard Model, gravity, early universe inflation, and condensed matter phenomena such as phase transitions, superconductors, and quantum Hall fluids. A triumph of 20th century physics was to understand weakly coupled QFTs: theories whose interactions can be treated as small perturbations of otherwise freely moving particles. However, weakly coupled QFTs represent a tiny island in an ocean of possibilities. They cannot capture many of the most interesting and important physical phenomena, from the strong nuclear force to high temperature superconductivity.

The critical challenge for the 21st century is to understand and solve strongly coupled QFTs. The Bootstrap collaboration tackles this critical problem from a myriad of different rigorous perspectives, consistency with general principles of symmetry and quantum mechanics being the central theme.

In three Week program, lectures and courses will occupy the mornings. The afternoons will be reserved to free discussions and spontaneously organized presentations.

Local Organizers: Francesco Aprile (Univ. Complutense – Madrid, Spain), Nathan Berkovits (ICTP-SAIFR/IFT-UNESP), Pedro Vieira (IFT-SAIFR-Perimeter, Brazil-Canada)

Organizing Committee: Joao Penedones (EPFL-Lausanne, Switzerland), Leonardo Rastelli (YITP, US), Slava Rychkov (IHES and ENS, France)

Scientific Advisory Committee: The members of the Simons Non-perturbative Bootstrap Collaboration.

Simons Collaborations, made possible by support from the Simons Foundation, bring together groups of outstanding scientists to address mathematical or theoretical topics of fundamental scientific importance in which a significant new development has created a novel area for exploration or provided a new direction for progress in an established field.
