Unifying Local Dynamics in Two-State Spin Systems
Serge Galam
We present a new two-state {+-} opinion dynamics model which defines a general frame to include all local dynamics in two-state spin systems. Agents evolve by probabilistic local r…
Restoring site percolation on a damaged square lattice
Serge Galam, Krzysztof Malarz
We study how to restore site percolation on a damaged square lattice with nearest neighbor (N) interactions. Two strategies are suggested for a density of destroyed sites b…
Spontaneous coalition forming: Why some are stable?
Serge Galam
A model to describe the spontaneous formation of military and economic coalitions among a group of countries is proposed using spin glass theory. Between each couple of countries,…
A 1-d Ising model for ripple formation
Nicolas Vandewalle, Serge Galam
A 1-d Ising model is shown to reproduce qualitatively the dynamics of ripple formation. Saltation effect is imposed using a Kawasaki dynamics and a pair interaction over some dista…
Behind the shirts, is symmetry
Serge Galam
The outbreak of spontaneous order in matter results from symmetry breaking. How does a system change its collective organisation ? How does it break its own symmetry ? That are the…
Comment on "A landscape theory of aggregation"
Serge Galam
The problem of aggregation processes in alignments is the subject of a paper published in a Statistical Physics Journal (Physica A 230 (1996) 174-188). Two models are presented and…
