Universal behavior for single-file diffusion on a disordered fractal
L. Padilla, H. O. Mártin, J. L. Iguain
We study single-file diffusion on a one-dimensional lattice with a random fractal distribution of hopping rates. For finite lattices, this problem shows three clearly different reg…
Transport in a chain of asymmetric cavities: Effects of the concentration with hard-core interaction
Gonzalo Suárez, Miguel Hoyuelos, Héctor Mártin
We studied the transport process of overdamped Brownian particles, in a chain of asymmetric cavities, interacting through a hard-core potential. When a force is applied in opposite…
Evolution equation for tagged particle density and correlations in single file diffusion
Gonzalo Suárez, Miguel Hoyuelos, Héctor O. Mártin
We derive and study a theoretical description for single file diffusion, i.e., diffusion in a one dimensional lattice of particles with hard core interaction. It is well known that…
Anisotropic anomalous diffusion modulated by log-periodic oscillations
L. Padilla, H. O. Mártin, J. L. Iguain
We introduce finite ramified self-affine substrates in two dimensions with a set of appropriate hopping rates between nearest-neighbor sites, where the diffusion of a single random…
Anomalous diffusion with log-periodic modulation in a selected time interval
L. Padilla, H. O. Mártin, J. L. Iguain
On certain self-similar substrates the time behavior of a random walk is modulated by logarithmic periodic oscillations on all time scales. We show that if disorder is introduced i…
Log-periodic oscillations for diffusion on self-similar finitely ramified structures
L. Padilla, H. O. Mártin, J. L. Iguain
Under certain circumstances, the time behavior of a random walk is modulated by logarithmic periodic oscillations. The goal of this paper is to present a simple and pedagogical exp…
