| الوصف: | Light propagation in random media is notorious for its resilience to (Anderson) wave localization. We here argue that in materials with slow helicity relaxation previously unnoticed principles of topology reinforce delocalization. We show that the effective electromagnetic action is governed by principles, identical to those protecting delocalization at topological insulator surface states. The length scales over which these exert a protective influence depend on the conservation of helicity, leading to the prediction that light scattering in media with, e.g., strong magnetic and electric dipolar resonances evades localization over large scales. Comment: 4 pages, supplemental material |
