  • How does one calculate the individual phonon dispersion curves from molecular dynamics simulation?

    Featured 15 Jun 2014 in Answers

    Asked by Daniel J Rogers - 5 years 4 months ago - 0 responses

    How does one calculate the phonon dispersion relations from the output of a molecular dynamics simuation? I have successfully calculated the complete phonon density of states using a fourier transform of the velocity autocorrelation function, but I am still confused as to how to calculate the...
