Physical reduced states and continuum characters of the lattice Kramers-Wannier defect
Yi Liang
The paper analytically determines the entanglement entropy of the Kramers‑Wannier duality defect in the critical Ising chain, proving it equals (1/2) log 2 and linking this result…

Entanglement fingerprint of a non-invertible symmetry: exact Fibonacci cut charges on the lattice
Yi Liang
Non-invertible defects are usually diagnosed through scaling spectra or infrared CFT data. We show that the Fibonacci duality defect of the critical golden chain already carries an…
