Longitudinal (a–b) and transverse (c–d) current-current correlation functions CL,T for k = 0.14, 0.30, 0.33, 0.39, 0.63, 1.2 (LJ units).
In the panels b and d, we provided an example of the fit with the DHO function given by Eq. (1) for k = 0.076 (solid line). Fit data are ΩT = 0.176, ΩL = 0.464, ΓT = 1.5 · 10−3, ΓL = 5.4 · 10−3.
