Unraveling the Physics and Chemistry of Water-Rich Mixtures at Extreme Pressures and Temperatures

Executive Summary

We will develop two new laser-driven dynamic compression platforms that will enable the unraveling of the new physics and chemistry of low atomic number mixtures, such as those rich in water, at unprecedented extreme temperatures and pressures. Results from the experiments will provide a better understanding of planet formation and evolution and provide insights into the properties of matter under extreme conditions.
