On finite-size scaling of the order parameter in percolation

Finite-size scaling of the order parameter O in the disordered phase is presented for percolation in 2d and 3d and compared to the behavior of the magnetization of the Ising model. We find that the order parameter O grows logarithmically with the system size L for p < p_c and thus the analogy with the Ising model is not complete. Furthermore we find evidence for scaling behavior of the type O ～ L^?y/v (p_c ? p)^β?y where the exponent y is not dv/2 as in the Is ing case.     

Unperturbed dimensions of cyclochain polymers

The conformational parameters of three polyoxadiazoles were calculated by a direct computer simulation assuming free rotation about virtual bonds. The results obtained proved to be close to those derived from viscosity and sedimentation experiments.
