Figure 4

Effect of the coupling constant \({\gamma }_{0}\) on the population of the donor site for (a) \(\tau =0.01\) fs, (b) \(\tau =10\) fs, and (c) \(\tau =100\) fs. [Note the difference in the scale in (a) in comparisons to (b) and (c)]. The inset of Fig. 4(b) shows a zoom of the population patterns to highlight short-lived quantum oscillations. (d) Figure showing the population of the dimer system for different values of \(({\gamma }_{0},\tau )\). This shows how increasing \(\tau \) (in units of femtoseconds) allows for lower values of the coupling coefficient to the environment (shown in units of cm⁻¹).
