Curvature Distribution of Worm-like Chains in Two and Three Dimensions
S. M. Rappaport, S. Medalion, Y. Rabin
Bending of worm-like polymers carries an energy penalty which results in the appearance of a persistence length l such that the polymer is straight on length scales smaller than l…
Differential Geometry of Polymer Models: Worm-like Chains, Ribbons and Fourier Knots
Shay M Rappaport, Yitzhak Rabin
We analyze several continuum models of polymers: worm-like chains, ribbons and Fourier knots. We show that the torsion of worm-like chains diverges and conclude that such chains ca…
Metastable tight knots in a worm-like polymer
Alexander Y. Grosberg, Yitzhak Rabin
Based on an estimate of the knot entropy of a worm-like chain we predict that the interplay of bending energy and confinement entropy will result in a compact metastable configurat…
DNA in nanopore-counterion condensation and coion depletion
Yitzhak Rabin, Motohiko Tanaka
Molecular dynamics simulations are used to study the equilibrium distribution of monovalent ions in a nanopore connecting two water reservoirs separated by a membrane, both for the…
Fluctuating Filaments Under Tension - From Flexible Chains to Rigid Rods
David A. Kessler, Yitzhak Rabin
We develop a novel biased Monte-Carlo simulation technique to measure the force-extension curves and the distribution function of the extension of fluctuating filaments stretched b…
On the deformation of spontaneously twisted fluctuating ribbons
S. Panyukov, Y. Rabin
A theoretical analysis of the effect of force and torque on spontaneously twisted, fluctuating elastic ribbons is presented. We find that when a filament with a straight center lin…
