Extended Data Fig. 10: Properties of the 2DSL model in the low temperature glassy state.

a, Configuration of particles with directional bondings. Green particles form isolated pentagons. b, Transverse dynamical structure factors, with fits to equation (1) in the main text (solid grey lines). The blue dotted and purple dashed lines represent log-normal contribution and phonon contribution at q = 1.295, respectively. The red dashed line denotes the boson peak frequency. c, Spatial distribution of the atomic-level vibrability around the boson peak frequency.
