Structural origin of the anomalous properties of SiO2 glass under pressure

Understanding the structural origin of the anomalous properties of SiO2 liquid and glass is fundamental not only in physics, but also in geophysics, in understanding the nature of silicate magmas in the Earth and other planets, and in materials science as a prototype network-forming glass. Theoretical studies of SiO2 liquid suggest that the second shell structure of silicon is the key to understanding the anomalous properties of SiO2 liquid at high temperatures and high pressures.
