The importance of the dynamic anomaly of the self-diffusion coefficient, which becomes zero at the colloidal glass transition volume fraction φg as DS∼(1−Φ(x,t)/φg)2, has recently been emphasized for understanding structural slowing down in concentrated hard-sphere colloidal suspensions,...

Monte Carlo simulations of a sheared Ising model are used to study nonequilibrium fluctuations of mechanical work. The validity of the transient (starting from equilibrium) and the steady state fluctuation relations is verified. A fluctuation relation has been also shown to hold for the...

Starting from the linearized fluctuating Boussinesq equations we derive an expression for the structure factor of fluids in stationary convection-free thermal nonequilibrium states, taking into account both gravity and finite-size effects. It is demonstrated how the combined effects of gravity...

We examine several recently suggested methods for the detection of long-range correlations in data series based on similar ideas as the well-established Detrended Fluctuation Analysis (DFA). In particular, we present a detailed comparison between the regular DFA and two recently suggested...

The self-diffusion of three 128-arm polybutadiene star solutions in toluene was investigated over a broad concentration range from dilute to the ordering region with pulsed field gradient NMR (PFG-NMR). The strong concentration dependence of the self-diffusion coefficient in the fluid state is...

A statistical-mechanical theory of slow dynamics near the glass transition in two kinds of glass-forming systems, (M) molecular systems and (S) suspensions of colloids, is presented from a unified point of view based on the Tokuyama–Mori projection operator method. The exact diffusion...

The dynamics of complex systems of soft condensed matter has been often measured to contain non-trivial power law scaling over some range. Here we investigate the dependence of dynamic scaling on system structure. We focus our attention on overdamped fractal networks as colloidal and polymer...

We have studied by means of high resolution Nuclear Magnetic Resonance the dynamical and structural properties of water/methanol solutions as a function of temperature and concentration. We measured dynamical quantities such as the self-diffusion coefficient and the spin–lattice relaxation...
