title = "High-pressure transformation of sio2 glass from a tetrahedral to an octahedral network: A joint approach using neutron diffraction and molecular dynamics",
abstract = "A combination of in situ high-pressure neutron diffraction at pressures up to 17.5(5) GPa and molecular dynamics simulations employing a many-body interatomic potential model is used to investigate the structure of cold-compressed silica glass. The simulations give a good account of the neutron diffraction results and of existing x-ray diffraction results at pressures up to ∼60GPa. On the basis of the molecular dynamics results, an atomistic model for densification is proposed in which rings are {"}zipped{"} by a pairing of five- and/or sixfold coordinated Si sites.",
