摘要：

The nonlinear σ model approach to Anderson localization is studied for third‐sound modes of a 4He film on a disordered substrate. The disorder is assumed to be spatially long‐range correlated. Gaussian and exponentially decaying correlations are considered. From the renormalization group equation a nonlinear equation is derived for the renormalized diffusion coefficient. The localization length and numerically calculated diffusion spectra are discussed. Copyright © 1990 WILEY‐VCH Verlag GmbH & Co. KGaA
