We present a numerical investigation of the density fluctuations in a model glass under cyclic shear deformation conditions. We demonstrate that in our model glass, the compressibility is suppressed in inherently minimally energetic structures, showing a hyperuniform trend at a density which is below the critical jamming density. At low shear amplitudes, i.e. below the yield amplitude, the system reaches an absorbent steady state in which density fluctuations are suppressed, revealing the clear fingerprint of hyperuniformity up to a finite length scale. The opposite scenario is observed above the yield amplitude, where density fluctuations are strongly enhanced. We demonstrate that the transition to this state is accompanied by a spatial phase separation into two distinct hyperuniform regions, as a consequence of shear band formation at amplitudes greater than the yield amplitude.

我们提出了在循环剪切变形条件下模型玻璃中密度波动的数值研究。我们证明，在我们的模型玻璃中，可压缩性在固有的最低能级结构中受到抑制，在低于临界干扰密度的密度下显示出超均匀的趋势。在低剪切振幅下，即在屈服振幅以下，系统达到吸收剂稳态，在该稳态下密度波动得到抑制，从而揭示了直至有限长度尺度的超均匀性的清晰指纹。在屈服幅度以上观察到相反的情况，密度波动大大增强。我们证明，向该状态的过渡伴随着空间相分离成两个不同的超均匀区域，
