AIP Advances, 2023 Brownian motion of charged particles in the presence of low-frequency, circularly polarized electromagnetic waves is discussed. By using the wave rest frame, the Langevin system including low-frequency waves can be treated as a periodic system with a ...

Equations for nonlinear diffusion
Lietuvos Matematikos Rinkinys, 2010 The diffusion is the result of Brownian movement and occurs with a finite velocity. We presented the nonlinear diffusion equation, with diffusion coefficient directly proportional to the impurities concentration.

Interplay between particle trapping and heterogeneity in anomalous diffusion
Communications Physics, 2023 Heterogeneous media diffusion is often described using position-dependent diffusion coefficients and estimated indirectly through mean squared displacement in experiments.

Brownian diffusion of fibers [PDF]
Aerosol Science and Technology, 2016 Motion of nanoparticles suspended in fluids are dominated by Brownian diffusion—a physical property well understood following the work by Einstein in 1905. While theoretical derivation and experimental measurement of the diffusion coefficients for spherical particles are well developed, such information is lacking for non-spherical particles as the ...

Diffusion of skyrmions: the role of topology and anisotropy
New Journal of Physics, 2020 We study the diffusive motion of metastable localized spin structures with various topological charges by combining atomistic spin model simulations with an extension to the Thiele equation taking into account translational and rotational degrees of ...

Impact of host phonons on interstitial diffusion
Scientific Reports, 2022 The net effect of host phonons on interstitial diffusion has remained as a fundamental knowledge gap in our current theories since the motions of the host atoms and interstitials were coupled in these theories. Here we study this effect through molecular
