Activated diffusiophoresis
Christian M. Rohwer, Mehran Kardar, Matthias Krüger
Perturbations of fluid media can give rise to non-equilibrium dynamics, which may in turn cause motion of immersed inclusions. We consider perturbations ("activations") that are lo…
Percolation of sites not removed by a random walker in dimensions
Yacov Kantor, Mehran Kardar
How does removal of sites by a random walk lead to blockage of percolation? To study this problem of correlated site percolation, we consider a random walk (RW) of steps o…
Ramifications of disorder on active particles in one dimension
Ydan Ben Dor, Eric Woillez, Yariv Kafri +2
The effects of quenched disorder on a single and many active run-and-tumble particles is studied in one dimension. For a single particle, we consider both the steady-state distribu…
Pair Dispersion in Dilute Suspension of Active Swimmers
Sergey Belan, Mehran Kardar
Ensembles of biological and artificial microswimmers produce long-range velocity fields with strong nonequilibrium fluctuations, which result in dramatic increase diffusivity of em…
Pinning of Diffusional Patterns by Non-Uniform Curvature
John R. Frank, Jemal Guven, Mehran Kardar +1
Diffusion-driven patterns appear on curved surfaces in many settings, initiated by unstable modes of an underlying Laplacian operator. On a flat surface or perfect sphere, the patt…
Bacterial range expansions on a growing front: Roughness, Fixation, and Directed Percolation
Jordan M. Horowitz, Mehran Kardar
Directed Percolation (DP) is a classic model for nonequilibrium phase transitions into a single absorbing state (fixation). It has been extensively studied by analytical and numeri…
