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…
Nonequilibrium phenomena in adjacent electrically isolated nanostructures
V. S. Khrapai, S. Ludwig, J. P. Kotthaus +2
We report on nonequilibrium interaction phenomena between adjacent but electrostatically separated nanostructures in GaAs. A current flowing in one externally biased nanostructure…
Nonequilibrium interactions between two quantum circuits
V. S. Khrapai, S. Ludwig, J. P. Kotthaus +2
We briefly overview our recent results on nonequilibrium interactions between neighboring electrically isolated nanostructures. One of the nanostructures is represented by an exter…
