Computer Simulation of the Dynamics of a Single Polymer Chain

We have carried out computer simulations of the dynamics of a model polymer chain in a solvent. We find that the structure function scales for different chain sizes N as a function of q=kN^ν with ν=0.6 {} exponent for the radius of gyration. Furthermore, S(q)~q^-5/3 over a wide range, as predicted by Edwards. Time-dependent correlation functions appear to scale as tN^α, with α2ν+1. The time-displaced structure function is of the form S(kN^ν,tN^α).
