The difference between the dielectric function at two consecutive iterations, <math>i</math> and <math>i+1</math> is computed as root-mean-square over the frequency grid sampling ::<math> \mathrm{RMS}[\epsilon] = \sqrt{\sum_{j=1}^N\le...")

While VASP possesses several methods to compute this function, here we focus on a <math>O(N^2)</math> strategy, which can be useful when dealing with large systems. ==Macroscopic polarizability as a time-dependent integral== The main argument is that one can write <math>\epsilon{ij}(\omega)</math> as a time-de...")
