Disordered photonics: from experiments to its supersymmetry field theory

Prof. Chushun Tian

Abstract

Very recent experiments have unveiled that classical wave transport through open random media exhibits very rich physics. In this talk, I will introduce two new wave phenomena: highly unconventional diffusion of Anderson localized waves and transition in transmission statistics of diffusive waves. Then, I will introduce a very powerful technique -- the supersymmetry field theory for waves in open random media -- which allows us on a full microscopic level to systematically explore this subject.
