Velocity Autocorrelation and Vibrational Spectrum Calculation

September 29, 2010

The velocity autocorrelation function (VAF) is usually calculated when one wishes to analyse the vibrational or diffusive properties of a system of atoms. […] If the motion of the atoms tends to an oscillatory pattern, the VAF will characterize the ossilations because the velocity of the atoms will self-correlate in a periodic fashion…

Why Every Physicist Should Know Python

If you deal with data sets that need to be processed, you almost certainly have (1) a series of programs or scripts that you use for processing or post-processing of data or (2) a detailed and tedious routine to push data around in columns in a spreadsheet software like QTI Plot, Excel, Origin or Gnumeric. Either way, Python can save you time and effort.
