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…
On the inner structure of confined positronium
Tamas Fulop, Zeno Farkas, Alfred Seeger +1
We study the inner structure of a positronium confined to a void by treating it as a two-particle quantum system where the electron is captured by an infinite potential well and th…
Agglomeration of Charged Nanopowders in Suspensions
J. H. Werth, M. Linsenbuehler, S. M. Dammer +4
The aim of this work is to understand agglomeration of charged powders suspended in nonpolar fluids. The concerted influence of electromagnetic, hydrodynamic and van der Waals forc…
