Abstract:
Self Assembly of particles under a radially symmetric two-body potential
was studied. The new potential was designed by us with the aim of modeling
polymeric chains. The self assembly, implemented through the off-lattice
Monte Carlo scheme, produced chain-like structures. The structures were
found to have branching, which, although remained after various attempts
to eliminate, was brought down to a minimum. The set of parameters of
potential was then optimized for maximum chain length with least branching.
The clustersize distribution was analyzed and found to have exponential
distribution. As a measure to reduce branching of the chains, the system was
confined between walls and was subjected to weak constant shear stress, implemented
using Molecular Dynamics scheme. The response of the system
was analyzed. The variation of the branching and clustersize when the system
was sheared with walls of various degrees of attraction was studied.
