Oscillations and patterns in interacting populations of two species
Matti Peltomaki, Martin Rost, Mikko Alava
Interacting populations often create complicated spatiotemporal behavior, and understanding it is a basic problem in the dynamics of spatial systems. We study the two-species case…
The effect of thresholding on temporal avalanche statistics
Lasse Laurson, Xavier Illa, Mikko J. Alava
We discuss intermittent time series consisting of discrete bursts or avalanches separated by waiting or silent times. The short time correlations can be understood to follow from t…
Three- and four-state rock-paper-scissors games with diffusion
Matti Peltomaki, Mikko Alava
Cyclic dominance of three species is a commonly occurring interaction dynamics, often denoted the rock-paper-scissors (RPS) game. Such type of interactions is known to promote spec…
Line creep in paper peeling
Jari Rosti, Juha Koivisto, Paola Traversa +3
The dynamics of a "peeling front" or an elastic line is studied under creep (constant load) conditions. Our experiments show an exponential dependence of the creep velocity on the…
Anomalous Roughness of Fracture Surfaces in 2D Fuse Models
Phani K. V. V. Nukala, Stefano Zapperi, Mikko Alava +1
We study anomalous scaling and multiscaling of two-dimensional crack profiles in the random fuse model using both periodic and open boundary conditions. Our large scale and extensi…
Crack Roughness in the 2D Random Threshold Beam Model
Phani K. V. V. Nukala, Stefano Zapperi, Mikko Alava +1
We study the scaling of two-dimensional crack roughness using large scale beam lattice systems. Our results indicate that the crack roughness obtained using beam lattice systems do…
