| Abstract: |
Frictional finger trees are patterns emerging from non-equilibrium processes in particle-fluid systems. Their formation share several properties with growth algorithms for minimal spanning trees in random energy landscapes. We propose that the frictional finger trees are indeed in the same geometric universality class as the minimal spanning trees, which is checked using updated numerical simulation algorithms for frictional fingers. We also propose a theoretical model for anomalous diffusion in these patterns, and discuss the role of diffusion as a tool to classify geometry. |
