新加坡南洋理工大学Simon Redfern教授研究组招收2021秋季博士生

研究课题:高压下材料结构预测

Pressure-driven routes to materialsdiscovery and planetary formation - abundant element compounds at highpressures.

We are familiar with the fact thatmatter changes state, due to driving free energy changes, as a function oftemperature or pressure - solid ice transforms to liquid water to gaseous steamas we heat it, or, transforms from solid to liquid as we add sodium chloride.The influence of pressure on matter is less-well studied, but is a muchstronger effect. The discovery of room temperature superconductivity inmixtures of carbon, sulfur and hydrogen recently* is a consequence of thehigh-density conditions of the mixture, held at more than two millionatmospheres’ pressure. Such extraordinary physical phenomena and physicalconditions can be achieved in laboratory experiments, and in computersimulations of materials, but they are also the conditions found deep inplanetary interiors. When pressure is applied, the interatomic distances inmaterials may change significantly, modifying bonding and electronic structure.Pressure is now recognized as an important, if sometimes brutal, force formodifying the structures and properties of materials, so it also offers newopportunities for creating new materials, for materials discovery, and forunveiling novel physical and chemical properties of materials. It is alsoimportant for understanding how planets and their moon satellites form, andultimately how dense matter in the universe behaves. The ten most abundantelements in our galaxy are H, He, O, C, Ne, Fe, N, Si, Mg and S. This projectwill take simple mixtures of light elements from this group (similar to the C-H-Ssuperconductors mentioned above) up to high pressure to explore the new physicsand chemistry that their combinations result in, to shed new light on materialsdiscovery, as well as on planetary formation, geophysical and geochemicalprocesses, and planetary evolution.
