Fig. 4: Atomic contributions to harmonic emission in ReS2.
From: Orbital perspective on high-harmonic generation from solids
The circles colors represent the six different atomic pairs, the size of each circle is proportional to the Fourier amplitude ∣An∣ and the Fourier phase φn is given in the vertical axis. The panels display the Fourier amplitudes ∣An∣ and phases φn of the six atomic pairs (inversion-symmetric partners) as a function of the laser polarization angle for H11. Two driver intensities are shown: a 0.1 TW/cm2 and b 0.6 TW/cm2. The results shown are for the harmonic polarization α that is parallel to the electric field.
