Fig. 5

The comparison is shown for 2 (a) and 5 (b) monolayers of WSe2: The full time dependent MQED framework (blue), 1st order MQED perturbation theory (orange), the full MQED framework while neglecting the dispersion of the intersubband transition energy (green), approximating the TMD as a dipole sheet at z0 = d/2 (red), and the point dipole approximation at z0 = d/2 (purple). The dashed black line marks the graphene Fermi level at which horizontal transitions are opened up.
