Abstract

A new application of the recently developed superbasin‐parallel replica (ParRep) method is presented. As a demonstration of this new application, mechanical properties of elastomeric networks of Lennard‐Jones polymer chains are calculated. In this application, superbasin boundaries are placed at locations in phase space corresponding to chain breakage. It is shown that placing superbasin boundaries at this natural location satisfies the prerequisites for using superbasin‐ParRep, and for the simulations conducted, leads to a near‐ideal scaling of wall clock time with the number of replicas, thereby demonstrating the potential for a drastic extension of simulation timescales for this class of systems.
