Current reversals in driven lattice gases and Brownian motion
Moritz Wolf, Sören Schweers, Philipp Maass
Particle currents flowing against an external driving are a fascinating phenomenon in both single-particle and interacting many-particle systems. Underlying physical mechanisms of…

Nonequilibrium phase transition in single-file transport at high crowding
Annika Vonhusen, Sören Schweers, Artem Ryabov +1
Driven particle transport in crowded and confining environments is fundamental to diverse phenomena across physics, chemistry, and biology. A main objective in studying such system…

Correlations of density and current fluctuations in single-file motion of hard spheres and in driven lattice gas with nearest-neighbor interaction
Sören Schweers, Gunter M. Schütz, Philipp Maass
We analyze correlations between density fluctuations and between current fluctuations in a one-dimensional driven lattice gas with repulsive nearest-neighbor interaction and in sin…
