Morphological transition between patterns formed by threads of magnetic beads
Danilo S. Borges, Hans J. Herrmann, Humberto A. Carmona +2
Magnetic beads attract each other forming chains. We pushed such chains into an inclined Hele-Shaw cell and discovered that they spontaneously form self-similar patterns. Depending…
Phase transitions in a conservative Game of Life
Andre P. Vieira, Eric Goles, Hans J. Herrmann
We investigate the dynamics of a conservative version of Conway's Game of Life, in which a pair consisting of a dead and a living cell can switch their states following Conway's ru…
Dynamics of extended Schelling models
A. P. Vieira, E. Goles, H. J. Herrmann
We explore extensions of Schelling's model of social dynamics, in which two types of agents live on a checkerboard lattice and move in order to optimize their own satisfaction, whi…
Sequential disruption of the shortest path in critical percolation
Oliver Gschwend, Hans J. Herrmann
We investigate the effect of sequentiallydisrupting the shortest path of percolation clusters at criticality by comparing it with the shortest alternative path. We measure the diff…
Congestion fronts of diffusing particles
Bastian Burger, Hans J Herrmann
We study two new models of two particle species invading a surface from opposite sides. Collisions of particles of different species lead to the formation of congestion fronts. One…
Elastic backbone defines a new transition in the percolation model
Cesar I. N. Sampaio Filho, José S. Andrade, Hans J. Herrmann +1
The elastic backbone is the set of all shortest paths. We found a new phase transition at above the classical percolation threshold at which the elastic backbone becomes d…
