Deblocking of interacting particle assemblies: from pinning to jamming
M. -Carmen Miguel, Jose S. Andrade, Stefano Zapperi
A wide variety of interacting particle assemblies driven by an external force are characterized by a transition between a blocked and a moving phase. The origin of this deblocking…

Boundary effects on flux penetration in disordered superconductors
Andre Auto Moreira, Jose S. Andrade, Josue Mendes Filho +1
We investigate flux penetration in a disordered type II superconductor by molecular dynamics simulations of interacting vortices. We focus on the effect of different boundary condi…

Extremum statistics in scale-free network models
Andre Auto Moreira, Jose Soares de Andrade, Luis A. Nunes Amaral
We investigate the statistics of the most connected nodes in scale-free networks. For a scale-free network model with homogeneous nodes, we show by means of extensive simulations t…
