Kinetic roughening in slow combustion of paper.
Results of experiments on the dynamics and kinetic roughening of one-dimensional slow-combustion fronts in three grades of paper are reported. Extensive averaging of the data allows a detailed analysis of the spatial and temporal development of the interface fluctuations. The asymptotic scaling properties, on long length and time scales, are well described by the Kardar-Parisi-Zhang (KPZ) equat...
متن کاملSelf-similar roughening of drying wet paper.
We studied the kinetic roughening dynamics of drying wet paper. The configurations of dry paper sheets are found to be self-similar, rater than self-affine. Accordingly, the paper roughening dynamics corresponds to the new class of anomalous kinetic roughening [J. J. Ramasco, J. M. López, and M. A. Rodríguez, Phys. Rev. Lett. 84, 2199 (2000)], characterized by the equal local and global roughne...
متن کاملDynamics of surface roughening with quenched disorder.
We study the dynamical exponent z for the directed percolation depinning (DPD) class of models for surface roughening in the presence of quenched disorder. We argue that z for d 1 1 dimensions is equal to the exponent dmin characterizing the shortest path between two sites in an isotropic percolation cluster in d dimensions. To test the argument, we perform simulations and calculate z for DPD, ...
متن کاملSurface dynamics below the roughening transition
~Ve consider conventional relaxation dynamics for surfaces, both evaporation dynamics and surface diffusion. We point out that the cusp singularity of the surface free energy implies that the relaxation dynamics has to be treated as a free boundary value problem. On this basis we predict, under appropriate conditions, the spontaneous formation of facets and a finite time of healing for the high
متن کاملFrom Surface Roughening to Qcd String Theory
There exists great interest and considerable effort to explain quark confinement in Quantum Chromodynamics (QCD) from the string theory viewpoint. The ideas of ’t Hooft, Polyakov, Witten, and others, and recent glueball spectrum or QCD string tension calculations in AdS theories are some illustrative examples of these activities. In a somewhat complementary approach, the search for a microscopi...
