ADE triality via (non-)invertible symmetry gauging

Abstract

It is long known that A-series minimal models and D-series minimal models are exchanged by gauging the invertible ${\mathbb{Z}}_2$ symmetry. More recently, it has been shown that A-series minimal models and E-series minimal models are exchanged by gauging a non-invertible symmetry. We complete the triality picture by showing that D-series minimal models and E-series minimal models are exchanged by gauging another non-invertible symmetry.
