Enhanced Diffusion of a Needle in a Planar Course of Point Obstacles
Felix Höfling, Erwin Frey, Thomas Franosch
The transport of an infinitely thin, hard rod in a random, dense array of point obstacles is investigated by molecular dynamics simulations. Our model mimics the sterically hindere…
Domain wall delocalization, dynamics and fluctuations in an exclusion process with two internal states
Tobias Reichenbach, Thomas Franosch, Erwin Frey
We investigate the delocalization transition appearing in an exclusion process with two internal states resp. on two parallel lanes. At the transition, delocalized domain walls for…
Statistical Mechanics of Semiflexible Bundles of Wormlike Polymer Chains
Claus Heussinger, Mark Bathe, Erwin Frey
We demonstrate that a semiflexible bundle of wormlike chains exhibits a state-dependent bending stiffness that alters fundamentally its scaling behavior with respect to the standar…
Traffic jams induced by rare switching events in two-lane transport
Tobias Reichenbach, Erwin Frey, Thomas Franosch
We investigate a model for driven exclusion processes where internal states are assigned to the particles. The latter account for diverse situations, ranging from spin states in sp…
