Perturbed phase-space dynamics of hard-disk fluids
The Lyapunov spectrum describes the exponential growth, or decay, of infinitesimal phase-space perturbations. The perturbation associated with the maximum Lyapunov exponent is strongly localized in space, and only a small fraction of all particles contributes to the perturbation growth at any instant of time. This fraction converges to zero in the thermodynamic large-particle-number limit. For ...
متن کاملMolecular dynamics simulation of a binary mixture lubricant for use in hard disk interfaces
In Hard Disk Drives (HDD), it is necessary to decrease the Flying Height (FH) between the head and the disk (currently, FH is around 3-5 nm) so as to increase recording densities. Retaining the solid lubricant has become a difficult proposition owing to intermittent contact between the surfaces. ZTMD and Z are used as solid lubricant to lubricate these interfaces. In this paper, the behavior of...

متن کاملLocalized and Delocalized Modes in the Tangent–Space Dynamics of Planar Hard Dumbbell Fluids
Systems of hard dumbbells are, arguably, the simplest model for a molecular fluid composed of linear molecules. We study here the Lyapunov instability for two-dimensional systems containing qualitatively different degrees of freedom, translation and rotation. We characterize this instability by the Lyapunov spectrum, which measures the rate of exponential divergence, or convergence, of infinite...
