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…
Comment on ``Self-organized criticality and absorbing states: Lessons from the Ising model"
Mikko J. Alava, Lasse Laurson, Alessandro Vespignani +1
According to Pruessner and Peters [Phys. Rev. E {\bf 73}, 025106(R) (2006)], the finite size scaling exponents of the order parameter in sandpile models depend on the tuning of dri…
Driven particle in a cloud of mobile impurities
Lasse Laurson, Mikko J. Alava
The dynamics of a test particle interacting with diffusing impurities in one dimension is investigated analytically and numerically. In the absence of an applied external force, th…
Dislocation interactions mediated by grain boundaries
Paolo Moretti, Lasse Laurson, Mikko J. Alava
The dynamics of dislocation assemblies in deforming crystals indicate the emergence of collective phenomena, intermittent fluctuations and strain avalanches. In polycrystalline mat…
Fluctuations in fluid invasion into disordered media
Martin Rost, Lasse Laurson, Martin Dube +1
Interfaces moving in a disordered medium exhibit stochastic velocity fluctuations obeying universal scaling relations related to the presence or absence of conservation laws. For f…
noise and avalanche scaling in plastic deformation
Lasse Laurson, Mikko Alava
We study the intermittency and noise of dislocation systems undergoing shear deformation. Simulations of a simple two-dimensional discrete dislocation dynamics model indicate that…
