Next, we have also considered dynamics corresponding to much lower temperatures. To do so, we launched a constant-energy trajectory with zero initial velocities. The resultant temperatures are less than 26 K (Fig. ). Expectedly, spectral broadening is smaller than that at 300 K (Fig. ). Importantly, the brightest excitons are more delocalized at low temperature, as revealed by the highest/lowest FTDM analysis (Fig. ).
