My PhD will be focused on using novel and traditional techniques to investigate Helium and Hydrogen at high pressures. This includes examining the structure of Phases II, III and IV of Hydrogen as part of the Hecate group at Edinburgh. Carrying on work from previous PhD projects I will attempt to gain insight in to these Phases by developing simplified models of their molecular interactions and look at developing novel techniques for predicting their Raman spectrum. Both high pressure Helium and Helium-Hydrogen mixtures will be investigated using density functional theory. The study of Helium will be focused on explaining the difference between the EOS and phase diagrams of its different isotopes. Studies of potential mixtures will look at both the stability of structures as well as the solubility of Helium in Hydrogen.

我的博士学位将专注于使用新颖和传统的技术来研究高压下的氦和氢。这包括研究氢的第二、第三和第四相的结构，作为爱丁堡Hecate集团的一部分。从以前的博士项目进行工作，我将试图通过开发分子相互作用的简化模型来深入了解这些阶段，并研究开发预测其拉曼光谱的新技术。高压氦和氦-氢混合物将使用密度泛函理论进行研究。氦的研究将集中在解释其不同同位素的状态方程和相图之间的差异。对潜在混合物的研究将着眼于结构的稳定性以及氦在氢中的溶解度。
