Extended Data Fig. 8: Dynamical structure factors of the 2DKA model in the low-temperature glassy state.

a, The transverse dynamical structure factors at several low wavenumbers, with the fits (solid grey lines) to equation (1) in the main text. The blue dotted and purple dashed lines denote the log-normal and phonon contributions for q = 0.941, respectively. b, The transverse dynamical structure factors at higher wavenumbers, with the fits (solid grey lines) to equation (1) in the main text. The blue dotted and purple dashed lines denote the log-normal and phonon contributions for q = 1.566, respectively. c,d, The longitudinal dynamical structure factors at the studied wavenumbers corresponding to a and b.
