Langevin picture of anomalous diffusion processes in expanding medium

X Wang, Y Chen - Physical Review E, 2023 - APS
The expanding medium is very common in many different fields, such as biology and
cosmology. It brings a nonnegligible influence on particle's diffusion, which is quite different …

Continuous time random walk in a velocity field: role of domain growth, Galilei-invariant advection-diffusion, and kinetics of particle mixing

F Le Vot, E Abad, R Metzler, SB Yuste - New Journal of Physics, 2020 - iopscience.iop.org
We consider the emerging dynamics of a separable continuous time random walk (CTRW)
in the case when the random walker is biased by a velocity field in a uniformly growing …

Continuous-time random walks and Fokker-Planck equation in expanding media

F Le Vot, SB Yuste - Physical Review E, 2018 - APS
We consider a separable continuous-time random walk model for describing normal as well
as anomalous diffusion of particles subjected to an external force when these particles …

Reaction-diffusion and reaction-subdiffusion equations on arbitrarily evolving domains

E Abad, CN Angstmann, BI Henry, AV McGann… - Physical Review E, 2020 - APS
Reaction-diffusion equations are widely used as the governing evolution equations for
modeling many physical, chemical, and biological processes. Here we derive reaction …

Phase transitions in the fractional three-dimensional Navier–Stokes equations

DW Boutros, JD Gibbon - Nonlinearity, 2024 - iopscience.iop.org
Abstract The fractional Navier–Stokes equations on a periodic domain [0, L] 3 differ from
their conventional counterpart by the replacement of the− ν∆ u Laplacian term by νsAsu …

Standard and fractional Ornstein-Uhlenbeck process on a growing domain

F Le Vot, SB Yuste, E Abad - Physical Review E, 2019 - APS
We study normal diffusive and subdiffusive processes in a harmonic potential (Ornstein-
Uhlenbeck process) on a uniformly growing or contracting domain. Our starting point is a …

Encounter-controlled coalescence and annihilation on a one-dimensional growing domain

F Le Vot, C Escudero, E Abad, SB Yuste - Physical Review E, 2018 - APS
The kinetics of encounter-controlled processes in growing domains is markedly different
from that in a static domain. Here we consider the specific example of diffusion-limited …

Langevin picture of subdiffusive particles under the joint influence of an expanding medium and an external constant force

X Wang, Y Chen - Physica A: Statistical Mechanics and its Applications, 2024 - Elsevier
It has been found that expanding medium has a nonnegligible influence on particle's
diffusion, the physical mechanism of which is quite different from an external force field. To …
