We present a joint theory, simulation and experimental study of collective and self-diffusion in concentrated suspensions of charged colloidal particles. The study is based on the generalized Smoluchowski diffusion equation accounting both for direct and solvent-mediated hydrodynamic interactions, and it spans the range from the colloidal short-time to the long-time regime. Owing to the large...

We present a method to derive analytically the growths exponents of a eroded surface whose dynamics is ruled by cellular automata. Starting from the automata, we write down the time evolution for the height's average and height's variance (roughness). We apply the method to the etching model[1,2] of $1+1$ dimensions, than we obtain the dynamical exponents, which perfectly match the...

We consider subdiffusion in a system which consists of two homogeneous media joined together; subdiffusion parameters can be different in both media [1,2]. We also consider subdiffusion with absorption in a composite system. The application of the theoretical model to describe a real diffusion processes in the considered system is also presented. Confronting the theoretical formulas with the...

We consider the random dynamics in a bounded domain, while concentrating on somewhat unexplored links between the absorbing and inaccessible boundarz data impact upon random motion. Both Brownian and Levy-stable dynamics will be discussed , with a focus on tyhe long term surival, and the permanent trapping scenarios.
