Gyration radius of a circular polymer under a topological constraint with excluded volume.
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 numerically evaluate the mean-square radius of gyration for ring polymers having a fixed knot type, where the ring polymers are given by self-avoiding polygons consisting of freely jointed hard cylinders. We obtain plots of the gyrati...
متن کاملOn the Apparent Radius of Gyration of Linear Polymers and the Experimental Determination of the Excluded - Volume Parameter
The structure factor for linear polymers in the 0 state is given by the well-known Debye function. In a good solvent the chain is subject to excluded volume; however, the form of the structure factor still closely resembles that of the Debye function. As a result, one is tempted to interpret the structure factor as a Debye function whose argument is scaled by the radius of gyration of the swoll...
متن کاملInterplay between chain stiffness and excluded volume of semiflexible polymers confined in nanochannels.
The properties of channel-confined semiflexible polymers are determined by a complicated interplay of chain stiffness and excluded volume effects. Using Pruned-Enriched Rosenbluth Method (PERM) simulations, we study the equilibrium properties of channel-confined polymers by systematically controlling chain stiffness and excluded volume. Our calculations of chain extension and confinement free e...
متن کاملRoles of stiffness and excluded volume in DNA denaturation.
The nature and the universal properties of DNA thermal denaturation are investigated by Monte Carlo simulations. For suitable lattice models we determine the exponent c describing the decay of the probability distribution of denaturated loops of length l, P approximately l(-c). If excluded volume effects are fully taken into account, c = 2.10(4) is consistent with a first order transition. The ...
متن کاملExcluded volume in protein side-chain packing.
The excluded volume occupied by protein side-chains and the requirement of high packing density in the protein interior should severely limit the number of side-chain conformations compatible with a given native backbone. To examine the relationship between side-chain geometry and side-chain packing, we use an all-atom Monte Carlo simulation to sample the large space of side-chain conformations...
