Cohesion induced deepening transition of avalanches
Chun-Chung Chen
A directed avalanche model with a control parameter is introduced to describe the transition between cohesive and noncohesive granular material. The underlying dynamics of the proc…
Directed avalanche processes with underlying interface dynamics
Chun-Chung Chen, Marcel den Nijs
We describe a directed avalanche model; a slowly unloading sandbox driven by lowering a retaining wall. The directness of the dynamics allows us to interpret the stable sand surfac…
An Interface View of Directed Sandpile Dynamics
Chun-Chung Chen, Marcel den Nijs
We present a directed unloading sand box type avalanche model, driven by slowly lowering the retaining wall at the bottom of the slope. The avalanche propagation in the two dimensi…
Active Width at a Slanted Active Boundary in Directed Percolation
Chun-Chung Chen, Hyunggyu Park, Marcel den Nijs
The width W of the active region around an active moving wall in a directed percolation process diverges at the percolation threshold p_c as W \simeq A ε^{-ν_\parallel} \ln(ε_0/ε),…
