Second order recurrence are established for a d-dimensional diffusion with an additive Wiener process, with switching, and with one recurrent and one transient regime and constant switching intensities, under suitable conditions. As a corollary, the rate of convergence towards the invariant regime of order t^{−2} is claimed. The approach is based on embedded Markov chains ...

First-principles modeling of exciton dynamics coupled with lattice vibrations is important for understanding exciton mobility, which is crucial for various applications. In order to shed light on such coupled exciton–lattice dynamics, in this paper, we use a restricted open-shell Kohn–Sham approach, which is a computationally efficient method for electronic structure calculations in the lowest excited ...

Injection-thermal treatment (ITT) of MIS structures in the mode of stepwise increase in highfield
injection current density bounded by the value of Jb, at which no noticeable processes of irreversible
charge degradation of the gate dielectric and its interface with the semiconductor occur, is under consideration.
The charge density injected into the gate dielectric during ITT should provide ...

The phenomenon of mode hybridization in the exchange-coupled two-layer antiferromagnet|ferromagnet structure has been theoretically investigated. Expressions describing the dependence of the resonant frequencies of magnetization oscillations on the external magnetic field have been obtained by the method of Hamiltonian formalism. The effect of the coupling strength between the ferro- and antiferromagnetic layers on the width ...

Chaotic variations in flow speed up mixing of scalar fields via intensified stirring. This paper addresses the statistical properties of a passive scalar field mixing in a regular shear flow with random fluctuations against its background. We consider two-dimensional flow with shear component dominating over smooth fluctuations. Such flow is supposed to model passive scalar ...

Microscopic description of solid Pb-O formation and dissolution in liquid lead coolant is important for the modelling of fast neutron reactors. For this purpose, in this work we develop interatomic potential models for lead melt with dissolved oxygen. Potentials fitting is based on \textit{ab initio} density functional theory (DFT) calculations and quantum molecular dynamics. Two ...

We study statistical properties of the passive scalar advection in a 2D flow that consist of a steady-state shear flow and a relatively weak smooth random component taking into account the effects of finite weak diffusion. The model is closely related to the dynamics of passive scalar transfer inside coherent vortices emerging as a result ...

We use 1H and 17O NMR static field gradient diffusometry to measure self-diffusion coefficients of protons (DH) and oxygens (DO) in Nafion 212 with various hydration levels (λ = 4–18). For all samples and both nuclei, we obtain activation energies (Ea) of ≈0.19 eV. Analyzing the hydration-level dependence of DH and DO, we find DO/DH ≈ 1 at λ ≈ 18, resembling ...

The paper presents a study of the behavior of room-temperature ionic liquids with different alkyl chain lengths and anion types in slit negatively charged carbon nanopores of various widths (1÷15 nm) using all-atom molecular dynamics simulations. The structure of the confined ionic liquids is investigated using number, mass, and charge density profiles and radial distribution ...

The influence of helium pressure on the mechanisms of diffusion of the He-filled nanobubbles in fcc Al is investigated by the classical molecular dynamics. It is shown that at pressures <20 kbar gas suppresses self-diffusion, while the concentration of adatoms, rather than their mobility, plays a key role. However, as the pressure increases to values at which ...

In this work, the kinetics of diffusion interaction of the molybdenum silicides Mo5Si3 + MoSi2 alloy with the zirconium-based E110 alloy is experimentally investigated. The structure and phase composition of diffusion couples subjected to vacuum annealing at 1100, 1200, and 1300°C for 3, 6, and 9 hours have been studied by scanning electron microscopy and ...

The temperature dependence of density is calculated for an aqueous solution of sucrose by the molecular dynamics method. The coefficients of viscosity and diffusion are also obtained in the 273–343 K range of temperatures. The hydrodynamic radius of a sucrose molecule in an aqueous solution is calculated. The obtained data are compared with the experimental ...
