SIMULATION STUDY OF POLYMER CHAIN GEOMETRY IN A ONE-DIMENSIONAL PERIODIC POTENTIAL

摘要

The behaviour of a freely-jointed chain in a one-dimensional periodic potential has been investigated by theory and simulation. Chain geometry is well described by perturbation theory in the limit of a weak potential. By contrast, predictions based on a tight-binding model for confinement acid layer-hopping of chains, are found to have much more restricted validity than previously conjectured.
