Residence time in presence of moving defects and obstacles

  author={Emilio N. M. Cirillo and Matteo Colangeli and A Di Francesco},
We discuss the properties of the residence time in presence of moving defects or obstacles for a particle performing a one dimensional random walk. More precisely, for a particle conditioned to exit through the right endpoint, we measure the typical time needed to cross the entire lattice in presence of defects. We find explicit formulae for the residence time and discuss several models of moving obstacles. The presence of a stochastic updating rule for the motion of the obstacle smoothens the… Expand


Residence time of symmetric random walkers in a strip with large reflective obstacles.
A one-dimensional (1D) analog of the 2D model where the role of the obstacle is played by two defect sites having smaller probability to be crossed with respect to all the other regular sites is developed, finding a perfect match with the Monte Carlo simulations. Expand
Localization of defects via residence time measures
We show that residence time measure can be used to identify the geometrical and transmission properties of a defect along a path. The model we study is based on a one--dimensional simple random walk.Expand
Conditional expectation of the duration of the classical gambler problem with defects
Abstract The effect of space inhomogeneities on a diffusing particle is studied in the framework of the 1D random walk. The typical time needed by a particle to cross a one-dimensional finite lane,Expand
On-site residence time in a driven diffusive system: Violation and recovery of a mean-field description.
Using mean-field theory, an analytical expression is obtained for the average on-site residence time defined as the time a particle spends on a given site before moving on to the next site using domain wall theory. Expand
Modeling transport through an environment crowded by a mixture of obstacles of different shapes and sizes
Many biological environments are crowded by macromolecules, organelles and cells which can impede the transport of other cells and molecules. Previous studies have sought to describe these effectsExpand
Controlling the transport of active matter in disordered lattices of asymmetrical obstacles.
The transport of active matter in the presence of a disordered square lattice of asymmetric obstacles, which is built by removing a fraction of them from the initial full lattice, achieves a spontaneous inversion of the net particle current. Expand

In normal lateral diffusion, the mean-square displacement of the diffusing species is proportional to time. But in disordered systems anomalous diffusion may occur, in which the mean-squareExpand
Anomalous dynamics of intruders in a crowded environment of mobile obstacles
A critical size asymmetry is discovered, at which anomalous collective transport of the small particles appears, manifested as a logarithmic decay of the density autocorrelation functions, and it is demonstrated that the matrix mobility is central for the observed anomalous behaviour. Expand
Nonequilibrium statistical mechanics of the zero-range process and related models
We review recent progress on the zero-range process, a model of interacting particles which hop between the sites of a lattice with rates that depend on the occupancy of the departure site. WeExpand
Gravity current flow over obstacles
When a gravity current meets an obstacle a proportion of the flow may continue over the obstacle while the rest is reflected back as a hydraulic jump. There are many examples of this type of flow,Expand
