Supersymmetric field theory of local light diffusion in semi-infinite media
arXiv:0712.3844 · doi:10.1103/PhysRevB.77.064205
Abstract
A supersymmetric field theory of light diffusion in semi-infinite disordered media is presented. With the help of this technique we justify--at the perturbative level--the local light diffusion proposed by Tiggelen, Lagendijk, and Wiersma [Phys. Rev. Lett. \textbf{84}, 4333 (2000)], and show that the coherent backscattering line shape of medium bar displays a crossover from two-dimensional weak to quasi-one-dimensional strong localization.
