Extended Data Fig. 6: Peak fitting of the \({{\boldsymbol{\Delta }}}_{{\bf{m}}}^{0}\) modes at v = 1/3, v = 2/3, v = 2/5 and v = 3/5 with θ = 10°.

The black open dots represent the experimental signals of the \({\varDelta }_{{\rm{m}}}^{0}\) modes in CP geometries (RR for v = 1/3 and v = 2/5, LL for v = 2/3 and v = 3/5). The grey dash lines indicate smoothed photoluminescence background signals. The black lines are the fitted Lorentzian peaks with small FWHM (29 μeV for v = 1/3, 33 μeV for v = 2/3, 30 μeV for v = 2/5 and 27 μeV for v = 3/5). The combination of these fitted Lorentzian peaks and photoluminescence background signals (the red dashed lines) gives a remarkable agreement to the measured RILS spectra. The sharpness of these peaks is noteworthy, as it indicates wavevector conservation in the scattering. PL, photoluminescence.
