dielectric_function()

program dielectric_function

A utility used to obtain the dielectric function from a kick calculation using the gauge field approach The approach follows the method described in Bertsch et al. PRB 62, 7998 (2000).

Currently, we only compute the dielectric function along the direction of the gauge field \(\hat{\alpha}=\frac{A_{\rm ext}}{|A_{\rm ext}|}\). We then compute

\[ $\epsilon^{-1}_{\alpha\alpha} = \frac{E_{\rm total}\cdot \hat{\alpha}}{E_{\rm ext}\cdot \hat{\alpha}} = \frac{E_{\rm ext}\cdot E_{\rm total}}{|E_{\rm ext}|^2}$. \]
