Lyapunov modes in soft-disk systems
Christina Forster, Harald A. Posch
Lyapunov modes are periodic spatial perturbations of phase-space states of many-particle systems, which are associated with the small positive or negative Lyapunov exponents. Altho…
Perturbed phase-space dynamics of hard-disk fluids
Christina Forster, Robin Hirschl, Harald A. Posch +1
The Lyapunov spectrum describes the exponential growth, or decay, of infinitesimal phase-space perturbations. The perturbation associated with the maximum Lyapunov exponent is stro…
Lyapunov instability and collective tangent space dynamics of fluids
Harald A. Posch, Christina Forster
The phase space trajectories of many body systems charateristic of simple fluids are highly unstable. We quantify this instability by a set of Lyapunov exponents, which are the rat…
Large-System Phase-Space Dimensionality Loss in Stationary Heat Flows
Harald A. Posch, William G. Hoover
Thermostated tethered harmonic lattices provide good illustrations of the phase-space dimensionality loss which occurs in the strange-attractor distributions characterizing station…
