Chaotic properties of spin lattices near second-order phase transitions
A. S. de Wijn, B. Hess, B. V. Fine
We perform a numerical investigation of the Lyapunov spectra of chaotic dynamics in lattices of classical spins in the vicinity of second-order ferromagnetic and antiferromagnetic…
Lyapunov instabilities in lattices of interacting classical spins at infinite temperature
A. S. de Wijn, B. Hess, B. V. Fine
We numerically investigate Lyapunov instabilities for one-, two- and three-dimensional lattices of interacting classical spins at infinite temperature. We obtain the largest Lyapun…
Largest Lyapunov exponents for lattices of interacting classical spins
A. S. de Wijn, B. Hess, B. V. Fine
We investigate how generic the onset of chaos in interacting many-body classical systems is in the context of lattices of classical spins with nearest neighbor anisotropic coupling…
Relating chaos to deterministic diffusion of a molecule adsorbed on a surface
Astrid S. de Wijn, Annalisa Fasolino
Chaotic internal degrees of freedom of a molecule can act as noise and affect the diffusion of the molecule on a substrate. A separation of time scales between the fast internal dy…
Equivalence of kinetic-theory and random-matrix approaches to Lyapunov spectra of hard-sphere systems
A. S. de Wijn
In the study of chaotic behaviour of systems of many hard spheres, Lyapunov exponents of small absolute value exhibit interesting characteristics leading to speculations about conn…
The Lyapunov spectrum of the many-dimensional dilute random Lorentz gas
Astrid S. de Wijn, Henk van Beijeren
For a better understanding of the chaotic behavior of systems of many moving particles it is useful to look at other systems with many degrees of freedom. An interesting example is…
