PhD project: Hot Dense Hydrogen

Project description

The behaviour of hydrogen, the most abundant element in the Universe, at high densities has been widely explored in recent years both experimentally and theoretically. These studies have yielded a wealth of information on the material, but detailed static compression experiments have generally been limited to low-temperatures (<300 K) and maximum pressures of ~300GPa. However, there are now numerous questions regarding the behaviour of hydrogen at high pressures and temperatures, the answers to which will have important implications for both fundamental physics and planetary science. In this project, optical spectroscopy will be used to constrain the behaviour of H2 (D2) at extreme compressions and elevated temperatures, searching for the predicted transition to a metallic superfluid state. In this project, you will use diamond anvil cells and external heating techniques combined with the optical spectroscopy (CSEC).
