The categorical data of the KW duality defect, including its quantum dimension sqrt(2), is encoded in the entanglement spectrum of the duality-twisted Ising ground state through a Majorana zero mode.
Generalized quantum dimensions from SymTFTs classify massless and massive RG flows in pseudo-Hermitian systems and relate coset constructions to domain walls.
