Entangled Polymer Rings in 2D and Confinement

Condensed Matter 2009-10-28 v2

Abstract

The statistical mechanics of polymer loops entangled in the two-dimensional array of randomly distributed obstacles of infinite length is discussed. The area of the loop projected to the plane perpendicular to the obstacles is used as a collective variable in order to re-express a (mean field) effective theory for the polymer conformation. It is explicitly shown that the loop undergoes a collapse transition to a randomly branched polymer with RlN14R\propto lN^\frac{1}{4}.
