Spontaneous Unknotting of a Polymer Confined in a Nanochannel
Wolfram Mobius, Erwin Frey, Ulrich Gerland
We study the dynamics of a knot in a semiflexible polymer confined to a narrow channel of width comparable to the polymers' persistence length. Using a combination of Brownian dyna…
Instability of spatial patterns and its ambiguous impact on species diversity
Tobias Reichenbach, Erwin Frey
Self-arrangement of individuals into spatial patterns often accompanies and promotes species diversity in ecological systems. Here, we investigate pattern formation arising from cy…
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…
Entangled Dynamics of a Stiff Polymer
Felix Höfling, Tobias Munk, Erwin Frey +1
Entangled networks of stiff biopolymers exhibit complex dynamic response, emerging from the topological constraints that neighboring filaments impose upon each other. We propose a…
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…
Self-Organization of Mobile Populations in Cyclic Competition
Tobias Reichenbach, Mauro Mobilia, Erwin Frey
The formation of out-of-equilibrium patterns is a characteristic feature of spatially-extended, biodiverse, ecological systems. Intriguing examples are provided by cyclic competiti…
