SymTFTs for Continuous non-Abelian Symmetries

Understand

Topological defects and operators give a far-reaching generalization of symmetries of quantum fields.

• An auxiliary topological field theory in one dimension higher than the QFT of interest, known as the SymTFT, provides a natural way for capturing such operators.
• This gives a new perspective on several applications of symmetries, but fails to capture continuous non-Abelian symmetries.
• The main aim of this work is to fill this gap.
