    • note
    • We can exclude the explanation of the photoexcitation of coherent longitudinal acoustic phonons (CLAPs) from the anisotropy of the coherent oscillations (Fig. 3) and damping. For KMO, the reflectivity (Ref. 17) and the optical conductivity (Ref. 13) is isotropic for wavelengths in the visible range, i.e., photon energy >2eV. Therefore, photoexcitation of CLAPs would result in polarization-independent (isotropic) oscillations of ΔR at 400 nm probe wavelength.

    • 3 since the reflectivity and optical conductivity is isotropic at photon energies above 2 eV (Refs. 13 and 17).

    • -1, i.e., larger than the biggest q probe used. Hence, we expect to generate a broad band of collective modes, comparable to the entire range of probe wavelengths.
