(In)commensurability, scaling and multiplicity of friction in nanocrystals and application to gold nanocrystals on graphite
Astrid S. de Wijn
The scaling of friction with the contact size and (in)commensurabilty of nanoscopic and mesoscopic crystals on a regular substrate are investigated analytically for triangular…
Internal degrees of freedom and transport of benzene on graphite
Astrid S. de Wijn
In this paper, the chaotic internal degrees of freedom of a benzene molecule adsorbed on a graphite substrate, their interplay with thermal noise, and their effects on the diffusio…
Lyapunov spectra of billiards with cylindrical scatterers: comparison with many-particle systems
Astrid S. de Wijn
The dynamics of a system consisting of many spherical hard particles can be described as a single point particle moving in a high-dimensional space with fixed hypercylindrical scat…
The Kolmogorov-Sinai entropy for dilute systems of hard particles in equilibrium
Astrid S. de Wijn
In an equilibrium system, the Kolmogorov-Sinai entropy, , equals the sum of the positive Lyapunov exponents, the exponential rates of divergence of infinitesimal p…
Goldstone modes in Lyapunov spectra of hard sphere systems
Astrid S. de Wijn, Henk van Beijeren
In this paper, we demonstrate how the Lyapunov exponents close to zero of a system of many hard spheres can be described as Goldstone modes, by using a Boltzmann type of approach.…
