Figure 2. Sharp symmetry change of nearest-neighbor structure.

Figure 2

(a) Amplitude of S1(α) distortion (left axis, blue curve) and full width half maximum of S1(α) (right axis, green curve) as a function of applied strain amplitude γ0. Both quantities show sharp transition at Inline graphic. The increasing amplitude of the distortion for Inline graphic indicates the growing distortion with increasing γ0. Sharp loss of distortion occurs at Inline graphic, where the two-fold symmetry vanishes, and the amplitude becomes essentially flat. (b) Order parameter C(β = π, γ0) of affine distortions shows sharp drop as a function of strain amplitude (left axis, blue). Also indicated are the elastic and viscous moduli, G′ and G′′ (right axis, green and black). Inset: Contour plot showing the evolution of the angular correlation function C(β, γ0) (see color bar) as a function of strain amplitude γ0 (vertical axis).
