Exclusion Processes with Avalanches
Uttam Bhat, P. L. Krapivsky
In an exclusion process with avalanches, when a particle hops to a neighboring empty site which is adjacent to an island the particle on the other end of the island immediately hop…
Lattice gases with a point source
P. L. Krapivsky, Darko Stefanovic
We study diffusive lattice gases with local injection of particles, namely we assume that whenever the origin becomes empty, a new particle is immediately injected into the origin.…
Survival of a static target in a gas of diffusing particles with exclusion
Baruch Meerson, Arkady Vilenkin, P. L. Krapivsky
Let a lattice gas of constant density, described by the symmetric simple exclusion process, be brought in contact with a "target": a spherical absorber of radius . Employing the…
Large Deviations in Single File Diffusion
P. L. Krapivsky, Kirone Mallick, Tridib Sadhu
We apply macroscopic fluctuation theory to study the diffusion of a tracer in a one-dimensional interacting particle system with excluded mutual passage, known as single-file diffu…
