Large-Scale Structure and Hyperuniformity of Amorphous Ices
Large-Scale Structure and Hyperuniformity of Amorphous Ices
We investigate the large-scale structure of amorphous ices and transitions between their different forms by quantifying their large-scale density fluctuations. Specifically, we simulate the isothermal compression of low-density amorphous ice (LDA) and hexagonal ice to produce high-density amorphous ice (HDA). Both HDA and LDA are nearly hyperuniform; i.e., they are …
