Query: Diffusion Mechanisms in Lithium Disilicate Melt by Molecular Dynamics
  Simulation   In this work we study the diffusion mechanisms in lithium disilicate melt
using molecular dynamics simulation, which has an edge over other simulation
methods because it can track down actual atomic rearrangements in materials
once a realistic interaction potential is applied. Our simulation results of
diffusion coefficients show an excellent agreement with experiments. We also
demonstrate that our system obeys the famous Stokes-Einstein relation at least
down to 1400 K, while a decoupling between relaxation and viscosity takes place
at a higher temperature. Additionally, an analysis on the dynamical behavior of
slow-diffusing atoms reveals explicitly the presence of dynamical
heterogeneities.
