Recently, the study of physical systems displaying longrange power-law correlation has attracted considerable attention. Long-range correlations have been found in a wide number of systems, includingâ€¦ (More)

Surfaces eroded by ion sputtering are sometimes observed to develop morphologies which are either ripple (periodic) or rough (nonperiodic). We introduce a discrete stochastic model that allows us toâ€¦ (More)

3D computer simulations and experiments are employed to study random packings of compressible spherical grains under external confining stress. In the rigid ball limit, we find a continuousâ€¦ (More)

Porous media, such as sedimentary rocks, have complex permeability fluctuations arising from the physical processes that formed them. These permeability fluctuations significantly affect the flow ofâ€¦ (More)

We analyze the transport properties of a neutral tracer in a carrier fluid flowing through percolationlike porous media with spatial correlations. We model convection in the mass transport processâ€¦ (More)

We perform a systematic study of several models that have been proposed for the purpose of understanding the motion of driven interfaces in disordered media. We identify two distinct universalityâ€¦ (More)

We consider a one-dimensional elastic string as a set of massless beads interacting through springs characterized by anisotropic elastic constants. The string, driven by an external force, moves in aâ€¦ (More)

A simple model for an interface moving in a disordered medium is presented. The model exhibits a transition between the two universality classes of interface growth in the presence of quenchedâ€¦ (More)
