Simulation study of dynamic features during the isothermal relaxation processes in supercooled liquid and glassy Pb

摘要：

　　The molecular dynamics simulations on the isothermal relaxation properties of supercooled liquid and glassy Pb have been performed.The calculated diffusion constant of Pb is well agreed with the experimental result.Results indicate that the relaxations of supercooled and glassy Pb present more and more pronounced heterogeneity with decreasing temperature.The appearance of the second plateau of mean square displacement (MSD) and the non-zero plateau of Non-Gaussian parameter (NGP) is corresponding to the rest of structure rearrangement.
