High resolution portrait of the ideal trefoil knot
Sylwester Przybyl, Piotr Pieranski
The shape of the most tight trefoil knot with N=200640 vertices found with an appropriately modified finite element method is analyzed. The high number of vertices makes plots of i…
The motion of the freely falling chain tip
W. Tomaszewski, P. Pieranski, J. -C. Geminard
The dynamics of the tip of the falling chain is analyzed. Results of laboratory experiments are presented and compared with results of numerical simulations. Time dependences of th…
Ropelength of tight polygonal knots
Justyna Baranska, Piotr Pieranski, Eric J. Rawdon
A physical interpretation of the rope simulated by the SONO algorithm is presented. Properties of the tight polygonal knots delivered by the algorithm are analyzed. An algorithm fo…
Gordian Unknots
P. Pieranski, S. Przybyl, A. Stasiak
Numerical simulations indicate that there exist conformations of the unknot, tied on a finite piece of rope, entangled in such a manner, that they cannot be disentangled to the tor…
The ideal trefoil knot
P. Pieranski, S. Przybyl
The most tight conformation of the trefoil knot found by the SONO algorithm is presented. Structure of the set of its self-contact points is analyzed.
Helical close packings of ideal ropes
S. Przybyl, P. Pieranski
Closely packed conformations of helices formed on the ideal rope are considered. The pitch versus radius relations which define a closely packed helix are determined. The relations…
