First-encounter time of two diffusing particles in two- and three-dimensional confinement
F. Le Vot, S. B. Yuste, E. Abad +1
The statistics of the first-encounter time of diffusing particles changes drastically when they are placed under confinement. In the present work, we make use of Monte Carlo simula…
First-encounter time of two diffusing particles in confinement
F. Le Vot, S. B. Yuste, E. Abad +1
We investigate how confinement may drastically change both the probability density of the first-encounter time and the related survival probability in the case of two diffusing par…
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 +1
We consider the dynamics of a separable Continuous Time Random Walk (CTRW) when the random walker is biased by a velocity field in a uniformly growing domain. Concrete examples for…
First-passage properties of mortal random walks: ballistic behavior, effective reduction of dimensionality, and scaling functions for hierarchical graphs
V. Balakrishnan, E. Abad, T. Abil +1
We consider a mortal random walker on a family of hierarchical graphs in the presence of some trap sites. The configuration comprising the graph, the starting point of the walk, an…
Continuous-time random-walk model for anomalous diffusion in expanding media
F. Le Vot, E. Abad, S. B. Yuste
Expanding media are typical in many different fields, e.g. in Biology and Cosmology. In general, a medium expansion (contraction) brings about dramatic changes in the behavior of d…
Optimal search strategies of space-time coupled random walkers with finite lifetimes
D. Campos, E. Abad, V. Méndez +2
We present a simple paradigm for detection of an immobile target by a space-time coupled random walker with a finite lifetime. The motion of the walker is characterized by linear d…
