University of Virginia, MSE 4270/6270: Introduction to Atomistic Simulations, Leonid Zhigilei Correlation functions and their application for the analysis of MD results 1. Introduction. Intuitive and quantitative definitions of correlations in time and space. 2. Velocity-velocity correlation function. the decay in the correlations in atomic motion along the MD trajectory. calculation of generalized vibrational spectra. calculation of the diffusion coefficient. 3. Pair correlation function (density-density correlation). analysis of ordered/disordered structures, calculation of average coordination numbers, etc. can be related to structure factor measured in neutron and X-ray scattering experiments.
