Frustrated bearings
R. S. Pires, A. A. Moreira, H. J. Herrmann +1
In a bearing state, touching spheres (disks in two dimensions) roll on each other without slip. Here we frustrate a system of touching spheres by imposing two different bearing sta…
A universal approach for drainage basins
Erneson A. Oliveira, Rilder S. Pires, Rubens S. Oliveira +3
Drainage basins are essential to Geohydrology and Biodiversity. Defining those regions in a simple, robust and efficient way is a constant challenge in Earth Science. Here, we intr…
Confined Sandpile in two Dimensions: Percolation and Singular Diffusion
R. S. Pires, A. A. Moreira, H. A. Carmona +1
We investigate the properties of a two-state sandpile model subjected to a confining potential in two dimensions. From the microdynamical description, we derive a diffusion equatio…
