Modelling investment in artificial stock markets: Analytical and Numerical Results
Roberto da Silva, Alexandre Tavares Baraviera, Silvio R. Dahmen
In this article we study the behavior of a group of economic agents in the context of cooperative game theory, interacting according to rules based on the Potts Model with suitable…
Static Versus Dynamic Friction: The Role of Coherence
Z. Farkas, S. R. Dahmen, D. E. Wolf
A simple model for solid friction is analyzed. It is based on tangential springs representing interlocked asperities of the surfaces in contact. Each spring is given a maximal stra…
Coupling between static friction force and torque
Silvio R. Dahmen, Zeno Farkas, Haye Hinrichsen +1
We show that the static friction force which must be overcome to render a sticking contact sliding is reduced if an external torque is also exerted. As a test system we study a pla…
Coupling between static friction force and torque for a tripod
Silvio R. Dahmen, Haye Hinrichsen, Andrey Lysov +1
If a body is resting on a flat surface, the maximal static friction force before motion sets in is reduced if an external torque is also applied. The coupling between the static fr…
