Transport in disordered optical systems — •Florian Heyder and Martina Hentschel — Institute for Physics, Theoretical Physics II/Computational Physics Group, Technische Universität Ilmenau, Weimarer Straße 25, 98693 Ilmenau, Germany

It has been shown that electron transport through a quantum point contact in a two-dimensional electron gas leads to branching patterns of the scattered trajectories. We numerically investigate an analogue that is realized by a 2D optical system where light rays experience a correlated refractive index. The results show a branching behavior as well. We further examine the trajectory-statistics in our disordered systems and find, amongst other, a connection between the correlation length of the refractive index and the persistence of the branching.
