Entanglement-spectrum fingerprint of a non-invertible symmetry: the Kramers--Wannier duality defect on the lattice
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.
