Fig. presents the MQC population dynamics with light-matter coupling strength of g c = 0.001 (panels (a), (d) and (g)), g c = 0.005 (panels (b), (e) and (h)), and g c = 0.01 (panels (c), (f) and (i)). The polariton population dynamics are obtained from both Ehrenfest dynamics (open circles in panels (d), (e) and (f)) as well as the FSSH approach (dots in panels (g), (h) and (i)), and compared to the numerically exact results (solid lines).
