摘要：

We derive a nonlinear supersymmetric a model for the transport of light (classical waves) through a disordered medium. We compare this model with the well-established nonlinear a model for the transport of electrons (Schrodinger waves) and display similarities of and differences between both cases. We show that for weak disorder both models are equivalent (have the same effective Lagrangian). This effective Lagrangian correctly reproduces the (different) Ward identities for Schrodinger waves and for classical waves.
