Thermodynamically Stable Knots in Semiflexible Polymers
Wolfhard Janke, Suman Majumder, Martin Marenz +1
Semiflexible polymers are widely used as a paradigm for understanding structural phases in biomolecules including folding of proteins. Here, we compare bead-spring and bead-stick v…
Knots are Generic Stable Phases in Semiflexible Polymers
Suman Majumder, Martin Marenz, Subhajit Paul +1
Semiflexible polymer models are widely used as a paradigm to understand structural phases in biomolecules including folding of proteins. Since stable knots are not so common in rea…
Stabilization and Destabilization of Semiflexible Polymers Induced by Spherical Confinement
Martin Marenz, Johannes Zierenberg, Wolfhard Janke
Spherical confinement can act either stabilizing or destabilizing on the collapsed state of a semi-flexible polymer. General free-energy arguments suggest that the order of the unc…
Percolation thresholds and fractal dimensions for square and cubic lattices with long-range correlated defects
Johannes Zierenberg, Niklas Fricke, Martin Marenz +3
We study long-range power-law correlated disorder on square and cubic lattices. In particular, we present high-precision results for the percolation thresholds and the fractal dime…
Scaling laws for random walks in long-range correlated disordered media
N. Fricke, J. Zierenberg, M. Marenz +3
We study the scaling laws of diffusion in two-dimensional media with long-range correlated disorder through exact enumeration of random walks. The disordered medium is modelled by…
Knots as Topological Order Parameter For Semi-Flexible Polymers
Martin Marenz, Wolfhard Janke
Using a combination of the replica-exchange Monte Carlo algorithm and the multicanonical method, we investigate the influence of bending stiffness on the conformational phases of a…
