Abstract
Quantum molecular dynamic simulations are introduced to study the shock compressed oxygen. The principal Hugoniot points derived from the equation of state agree well with the available experimental data. With the increase of pressure, molecular dissociation is observed. Electron spin polarization determines the electronic structure of the system under low pressure, while it is suppressed around 30 50 GPa. Particularly, nonmetal-metal transition is taken into account, which also occurs at about 30 50 GPa. In addition, the optical properties of shock compressed oxygen are also discussed.
