Conformation and Dynamics of a Self-Avoiding Sheet: Bond-Fluctuation Computer Simulation
Physics and Astronomy
Mathematics and Natural Sciences
The conformation and dynamics of a self-avoiding sheet are analyzed by the bond-fluctuating Monte Carlo method. The mean-square displacement of the center of mass of the sheet and that of its center node (R-n(2)) show dsymptotic diffusive behavior. The segmental dynamics in short and long time regimes can be deduced from the motion of the center node described by the power law R-n(2) similar or equal to C(1)t(2 mu) + C(2)t(2x) with mu similar or equal to 0.13 and v similar or equal to 1/2, where C-1 and C-2 are fitting constants and t is the time. The radius of gyration, Rg, scales with the linear size, L-s, of the sheet as R-g similar or equal to N-gamma with gamma similar or equal to 1/2 and N = L-s(2) and this is consistent with the conformational analysis of open tethered membranes with excluded-volume constraints.
