Phase Transitions of Single Semi-stiff Polymer Chains
We study numerically a lattice model of semiflexible homopolymers with nearest neighbor attraction and energetic preference for straight joints between bonded monomers. For this we use a new Monte Carlo algorithm, the ‘Pruned-Enriched Rosenbluth Method’ (PERM). It is very efficient both for relatively open configurations at high temperatures, and for compact and frozen-in low-T states. This all...
متن کاملConformations of single polymer chains on surfaces
Frontali et al. [137] showed in 1979 that it is possible to characterize the structure of polymers by analyzing high resolution microscopy images. The authors adsorbed DNA molecules onto mica and imaged them using electron microscopy. From the vectorized contours of single chains, they were able to determine both contour and persistence lengths so that the polymers were fully described in the f...

متن کاملPhase transitions of a single polymer chain: A Wang-Landau simulation study.
A single flexible homopolymer chain can assume a variety of conformations which can be broadly classified as expanded coil, collapsed globule, and compact crystallite. Here we study transitions between these conformational states for an interaction-site polymer chain comprised of N=128 square-well-sphere monomers with hard-sphere diameter sigma and square-well diameter lambdasigma. Wang-Landau ...
متن کاملNUMERICAL SIMULATIONS OF THE PHASE TRANSITIONS IN CLUSTERS
We have studied the phase transitions in atomic clusters by molecular dynamics simulation, assuming Lennard-Jones interatomic pair potential. Calculations are performed by DAP parallel computer. The results are analyzed by simulating their orientational distribution plots (dot-plot), and neutron diffraction patterns. It is shown that all the main features of the bulk phase transitions are e...
