摘要：
The non-Hermitian Aubry-Andr'e-Harper model exhibits a non-Hermitian phase transition that coincides with a localization transition. We provide a high-resolution measurement of the Butterfly spectrum and propose experiments to measure those transitions, using a photonic lattice. (C) 2021 The Author(s)
