Wang-Landau simulation of short single polyethylene chain's "crystallization" — •Timur Shakirov and Wolfgang Paul — University of Halle, Halle, Germany

The phase behaviour of polyethylene has been under wide investigation during the last 6 decades. But investigation of single chain crystallization is a technically difficult problem. In the case of molecular dynamics simulations, it is not so easy to distinguish kinetic and thermodynamic effects on chain folding. We present results of a Wang-Landau type Monte Carlo study at thermodynamical equilibrium of folding of a single polymer chain. Our simulations are based on a chemically realistic united atom model [1].
