Unjamming due to local perturbations in granular packings with and without gravity
M. Reza Shaebani, Tamas Unger, Janos Kertesz
We investigate the unjamming response of disordered packings of frictional hard disks with the help of computer simulations. First, we generate jammed configurations of the disks a…
Emergence of communities in weighted networks
J. M. Kumpula, J. -P. Onnela, J. Saramaki +2
Topology and weights are closely related in weighted complex networks and this is reflected in their modular structure. We present a simple network model where the weights are gene…
Fluctuation scaling in complex systems: Taylor's law and beyond
Zoltan Eisler, Imre Bartos, Janos Kertesz
Complex systems consist of many interacting elements which participate in some dynamical process. The activity of various elements is often different and the fluctuation in the act…
Unjamming of Granular Packings due to Local Perturbations: Stability and Decay of Displacements
M. Reza Shaebani, Tamas Unger, Janos Kertesz
We study the mechanical response generated by local deformations in jammed packings of rigid disks. Based on discrete element simulations we determine the critical force of the loc…
Random walks on complex networks with inhomogeneous impact
Zoltan Eisler, Janos Kertesz
In many complex systems, for the activity f(i) of the constituents or nodes i, a power-law relationship was discovered between the standard deviation sigma(i) and the average stren…
The effect of contact torques on porosity of cohesive powders
Guido Bartels, Tamas Unger, Dirk Kadau +2
The porosity of uniaxially compacted cohesive powders depends on the applied stress (including gravity). The case, where these stresses are weak, is considered. The compaction resu…
