About
Our group aims to understand novel properties of strongly correlated materials by utilizing first-principle methods from the input of atomic positions. Strongly correlated materials exhibit novel electronic properties such as the metal-insulator transition, charge density wave, magnetism, superconductivity, and topological phases. These properties are easily tunable by applying pressure, temperature, strains, and chemical dopings. Density functional theory (DFT) is generally insufficient in describing these novel properties quantitatively since it can not capture the effect of strong electronic interactions. Our group focuses on implementing and performing state-of-the-art computational methods based on dynamical mean field theory (DMFT) to understand the role of strong electronic correlations in various forms of materials, including crystal structures with defects and novel magnetism.
