By the development and investigation of coarse-grained models for ion motion in disordered systems, important progress has been achieved in the past to explain a large variety of ion transport properties in amorphous materials. In this work we discus

Cooperative charge relaxation within a random system of electrostatically interacting defect centers provides a mechanism for a “nearly constant dielectric loss” (NCL) response in structurally disordered ionic conductors. Pertinent models based o

Recent theories for the surface growth are reviewed, which describe the nucleation kinetics of binary alloys in the first layer and the nucleation on top of islands in the second layer. In the first part, describing the submonolayer regime, scaling r

Frequency-independent dielectric loss spectra constitute an ubiquitous phenomenon in strongly disordered materials. The degree of universality of this effect calls for a microscopic model that takes into account interactions and structural disorder,

The growth of binary-alloy clusters on a weakly interacting substrate through codeposition of two atomic species is studied by kinetic Monte Carlo simulation. Our model describes salient features of CoPt 3 nanoclusters, as obtained recently by the mo

Ordering processes in fcc-alloys with composition A_3B (like Cu_3Au, Cu_3Pd, CoPt_3 etc.) are investigated by Monte Carlo simulation within a class of lattice models based on nearest-neighbor (NN) and second-neighbor (NNN) interactions. Using an atom

Mean-field kinetic equations are a valuable tool to study the atomic dynamics and spin dynamics of simple lattice gas and Ising models. They can be derived from the microscopic master equation of the system and contain analytical expressions for kine

Motions of charged defects in ionic solids, including glassy ionic conductors, defective crystals and composite materials, imply slow relaxation processes, which are observable within a wide range of timescales larger than microscopic (vibrational) t
