Quantum field theory (QFT) is a universal language of modern theoretical physics. Originally developed to describe the interaction of light and matter, QFT has since found spectacular applications in particle, condensed matter, and statistical physics, as well as in cosmology and string theory. Some of the most profound open problems about the physics of non-topological QFTs – especially at strong coupling, beyond the reach of conventional techniques – are newly accessible thanks to recent developments in topological quantum field theory (TQFT). This insight comes with a dramatic evolution of the notion of symmetries in QFT: symmetries can be characterized via topological defects of various codimensions whose multidimensional fusion generalizes wildly the notion of groups to what are called categorical symmetries. This Nordita program is devoted to the exploration of these aspects of symmetries and their physical applications. We plan to have an interactive setting alternating lectures and seminars aiming at nourishing collaborations and stimulate further this rapidly evolving field.

The main aim of the meeting is to:

  • explore higher structure of global symmetries
  • study dynamical consequences of categorical symmetries
  • develop interdisciplinary interactions across hep-th, cond-mat and math

Program schedule

Workshop talks start at 10:30, with a short break from 11:30-12:00.
