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…
