Abstract
Understanding the structural origin of the anomalous properties of SiO2 liquid and glass at high pressures is fundamental in wide range of scientific fields. Here, the authors find experimental evidence of a bimodal behavior in the translational order of silicon’s second shell and breaking of local tetrahedral symmetry in SiO2 glass under pressure.
