Absolute negative mobility of an active tracer in a crowded environment
Pierre Rizkallah, Alessandro Sarracino, Olivier Bénichou +1
Absolute negative mobility (ANM) refers to the situation where the average velocity of a driven tracer is opposite to the direction of the driving force. This effect was evidenced…
Tracer diffusion in crowded narrow channels. Topical review
O. Benichou, P. Illien, G. Oshanin +2
We summarise different results on the diffusion of a tracer particle in lattice gases of hard-core particles with stochastic dynamics, which are confined to narrow channels -- sing…
Nonequilibrium fluctuations and enhanced diffusion of a driven particle in a dense environment
Pierre Illien, Olivier Bénichou, Gleb Oshanin +2
We study the diffusion of a tracer particle driven out-of-equilibrium by an external force and traveling in a dense environment of arbitrary density. The system evolves on a discre…
Nonlinear response and emerging nonequilibrium micro-structures for biased diffusion in confined crowding environments
O. Bénichou, P. Illien, G. Oshanin +2
We study analytically the dynamics and the micro-structural changes of a host medium caused by a driven tracer particle moving in a confined, quiescent molecular crowding environme…
Diffusion and subdiffusion of interacting particles on comb-like structures
O. Bénichou, P. Illien, G. Oshanin +2
We study the dynamics of a tracer particle (TP) on a comb lattice populated by randomly moving hard-core particles in the dense limit. We first consider the case where the TP is co…
Microscopic theory for negative differential mobility in crowded environments
O. Bénichou, P. Illien, G. Oshanin +2
We study the behavior of the stationary velocity of a driven particle in an environment of mobile hard-core obstacles. Based on a lattice gas model, we demonstrate analytically tha…
