Inverse Anderson transition in photonic cages

Transport inhibition via Anderson localization is ubiquitous in disordered periodic lattices. However, in crystals displaying only flatbands, disorder can lift macroscopic band flattening, removing geometric localization and enabling transport in certain conditions. Such a striking phenomenon, dubbed inverse Anderson transition and predicted for three-dimensional flatband systems, has thus far not been directly observed. Here we suggest a simple quasi one-dimensional photonic flatband system, namely, an Aharonov–Bohm photonic cage, in which correlated binary disorder induces an inverse Anderson transition and ballistic transport.
