The paper describes diffusion of particles in a tilted spatially periodic potential under the action of external forces in the case of a low friction. It is shown that in underdamped systems, a region of temperature-abnormal diffusivity (TAD) exists,

This scientific paper studies the abnormal diffusion of particles in spatially periodic structures exposed to the action of time –periodic rectangular fields. A choice of such a type of the field is related to the need of finding out physical reaso

The heterogeneity effect on the shielding efficiency of laminated composites under electron and gamma irradiation of moderate (~MeV) energies was studied. The effect was quantified, by means of Monte Carlo method, in terms of the asymmetry of the bim

This paper delves into the abnormal surface diffusion of particles in external time-periodic field. The relationship of surface diffusion enhancement as a function of amplitude and frequency of external fields has been studied. It has been shown that

We revisit the problem of diffusion in a driven system consisting of an inertial Brownian particle moving in a symmetric periodic potential and subjected to a symmetric time-periodic force. We reveal parameter domains in which diffusion is normal in

The diffusion of particles in tilted spatially periodic potentials in systems with different friction coefficients γ' has been studied in a wide temperature range. It has been shown that temperature-abnormal diffusivity is observed in a certain forc

We reassess the ‘dispersionless transport regime’ of Brownian particles in tilted periodic potentials. We show that the particles exhibit normal diffusive motion right after transitioning into the running state dragged by the constant bias force.

Recently, both the experimental data and the data of theoretical research appeared stating that the diffusion coefficient shows nonmonotonic behavior with temperature. The motion of Brownian particles in the space periodic structures is an example of

Vanadium or its alloy-based hydrides are intensively studied at the moment with regard to their use as hydrogen absorbents. Most experiments were carried out using “bulk” materials. This paper uses ion beam-assisted deposition technology (IBAD) t
