A scaling theory of local field fluctuations and optical nonlinearities is developed for random
metal-dielectric composites near a percolation threshold. The theory predicts that in the …

We review and discuss recent progress in modelling non-linear and non-local transport
processes in heterogeneous media. The non-locality that we consider is caused by long …

Concepts, methods and techniques of statistical physics in the study of correlated, as well as
uncorrelated, phenomena are being applied ever increasingly in the natural sciences …

Disorder and long-range interactions are two of the key components that make material
failure an interesting playfield for the application of statistical mechanics. The cornerstone in …

We report experimental results describing the mechanical breakdown of random porous Au
which is a new material specifically developed for this study. Digital image analysis was …

Local electromagnetic field fluctuations and related enhancement of nonlinear phenomena
in metal-dielectric composites near the percolation threshold (percolation composites) have …

We study via simulation how a lattice breaks if each bond is an elastic beam having
longitudinal and flexural breaking thresholds randomly selected according to various …

We report results of the tensile properties of nanoporous gold (NPG) as a function of the
density and average ligament diameter. As-dealloyed tensile samples were thermally …

Surface-enhanced optical nonlinearities are studied in a semicontinuous film consisting of
metal granules randomly distributed on an insulating substrate. The local fields are very …

We study the approach to global breakdown in disordered media driven by increasing
external forces. We first analyze the problem by mean-field theory, showing that the failure …
