Transitions from low-density state towards high-density state in stochastic bistable plasma-condensate systems
A. V. Dvornichenko, V. O. Kharchenko, D. O. Kharchenko
In this article we study transitions from low-density states towards high-density states in bistable plasma-condensate systems. We take into account an anisotropy in transference o…
Phase field modelling voids nucleation and growth in binary systems
D. O. Kharchenko, V. O. Kharchenko, Y. M. Ovcharenko +4
We present a comprehensive study of voids formation, nucleation and growth in a prototype model of binary alloys subjected to irradiation by using a combined approach based on phas…
Persistent Sinai type diffusion in Gaussian random potentials with decaying spatial correlations
Igor Goychuk, Vasyl O. Kharchenko, Ralf Metzler
Logarithmic or Sinai type subdiffusion is usually associated with random force disorder and non-stationary potential fluctuations whose root mean squared amplitude grows with dista…
Anomalous features of diffusion in corrugated potentials with spatial correlations: faster than normal, and other surprises
Igor Goychuk, V. O. Kharchenko
Normal diffusion in corrugated potentials with spatially uncorrelated Gaussian energy disorder famously explains the origin of non-Arrhenius temperature-depen…
Modeling self-organization of nano-size vacancy clusters in stochastic systems subjected to irradiation
Dmitrii O. Kharchenko, Vasyl O. Kharchenko, Anna I. Bashtova
A study of the self-organization of vacancy clusters in irradiated materials is presented. Using a continuum stochastic model we take into account dynamics of point defects and the…
Subdiffusive rocking ratchets in viscoelastic media: transport optimization and thermodynamic efficiency in overdamped regime
Vasyl O. Kharchenko, I. Goychuk
We study subdiffusive overdamped Brownian ratchets periodically rocked by an external zero-mean force in viscoelastic media within the framework of non-Markovian Generalized Langev…
