Our research interests focus on understanding the physics and chemistry of earth materials and condensed matters under in extreme high pressures and high/low temperature environments. We focus on experimental efforts by conducting high-pressure experiments mostly using DAC devices coupled with synchrotron X-ray, laser spectroscopic, and other lab-based measurements. We are particularly interested in the following research topics:
– Understanding the physics and chemistry (mineral physics) of the Earth’s interior and planetary bodies;
– 2-dimensional materials in extreme environments (TMDs, graphene, heterostructural compounds);
– Pressure-induced electronic, magnetic, elastic, and structural changes on earth materials and transition metal d/f compounds;
– Time-resolved laser spectroscopy, inelastic X-ray spectroscopies (HERIX, NRIXS, XES, RXES, RIXS, SMS, etc), and high-pressure techniques;
For the area of the mineral physics research, our main area of research interest focuses on understanding the nature of the Earth’s interior and other planetary bodies through direct examination of the properties of planetary materials under high pressure-temperature conditions. We use high pressure-temperature diamond anvil cells combined with in-house optical laser and synchrotron-based X-ray facilities to understand mineral physic of the deep-Earth materials. These studies aim to understand crystal structures, phase relations, physical and transport properties (e.g., sound velocities, electronic spin transitions, equation of state, etc), and chemical reactions of planetary materials under extreme high pressure temperature conditions. We aim to combine results from other disciplines to enhance our understanding of the interiors of the Earth and other planets.
Another research interest focuses on high pressure condensed matter physics and materials sciences in which we explore materials properties under extreme environments. The diamond cell technique coupled with synchrotron X-ray spectroscopies is well suited for this area of research. We are particularly interested in understanding the properties of superconductors (pnictides and cuprates), multi/nano-layered and superhard materials, transition metal and strongly correlated systems in extreme pressure-temperature environments.
