Elastic lines on splayed columnar defects studied numerically
Viljo Petaja, Matti Sarjala, Mikko Alava +1
We investigate by exact optimization method properties of two- and three-dimensional systems of elastic lines in presence of splayed columnar disorder. The ground state of many lin…
No self-similar aggregates with sedimentation
M. Peltomaki, E. K. O. Hellen, M. J. Alava
Two-dimensional cluster-cluster aggregation is studied when clusters move both diffusively and sediment with a size dependent velocity. Sedimentation breaks the rotational symmetry…
Self-organized criticality as a phase transition
Mikko Alava
The original sandpile model of Bak, Tang and Wiesenfeld from 1987 has inspired lots of consequent work and further ideas of how to describe the birth of scale-invariant statistics…
Self-organized criticality and interface depinning transitions
K. B. Lauritsen, M. J. Alava
We discuss the relation between self-organized criticality and depinning transitions by mapping sandpile models to equations that describe driven interfaces in random media. This e…
