Theory of Anderson Localization of Light in Real World Disordered Samples — •Regine Frank¹ and Andreas Lubatsch² — ¹Institute for Theoretical Physics, Eberhard-Karls University Tübingen, Germany Center for Light-Matter-Interaction, Sensors and Analytics (LISA+) and Center for Complex Quantum Phenomena (CQ) — ²Electrical Engineering, Precision Engineering, Information Technology, Georg-Simon-Ohm University of Applied Sciences, Kesslerplatz 12, 90489 Nürnberg, Germany

To derive Anderson localization of light is one of the holy grails of our time [1]. We show in this talk theoretical results derived by Vollhardt-Wölfle theory of photons[2,3,4] in 3D disordered, finite sized real world systems. Signatures of Anderson localized states are determined and they can be clearly distinguished from extended light-matter bound states as well as frequency converted photons and losses.
