Modelling the Entropic Pressure near a Ring Polymer Janse van Rensburg, Esaias J

Description

The entropic pressure in the vicinity of a ring polymer in a good solvent is modelled in the square and cubic lattices by sampling lattice polygons using a Monte Carlo method. I shall explain the scaling of the pressure and present numerical data confirming the scaling analysis in the square lattice. In addition, some preliminary results for the pressure near lattice polygons attached to a hard wall will be presented in the square and cubic lattices. In three dimensions these polygons can be knotted, and that will have an effect on the pressure. Joint work with Farid Gassoumov.
