Gyration radius of a circular polymer under a topological constraint with excluded volume
Miyuki K. Shimamura, Tetsuo Deguchi
It is nontrivial whether the average size of a ring polymer should become smaller or larger under a topological constraint. Making use of some knot invariants, we evaluate numerica…
Topological entropy of a stiff ring polymer and its connection to DNA knots
Miyuki K. Shimamura, Tetso Deguchi
We discuss the entropy of a circular polymer under a topological constraint. We call it the {\it topological entropy} of the polymer, in short. A ring polymer does not change its t…
On the Dominance of Trivial Knots among SAPs on a Cubic Lattice
Akihisa Yao, Hiroshi Matsuda, Hiroshi Tsukahara +2
The knotting probability is defined by the probability with which an -step self-avoiding polygon (SAP) with a fixed type of knot appears in the configuration space. We evaluate…
Characteristic length of random knotting for cylindrical self-avoiding polygons
Miyuki K. shimamura, Tetsuo Deguchi
We discuss the probability of random knotting for a model of self-avoiding polygons whose segments are given by cylinders of unit length with radius . We show numerically that t…
