Areas of Research Interests/ Research Projects
I am interested in the intersection of condensed matter physics and materials science, particularly focusing on bridging the frontier of condensed matter theory, such as topological order, fractionalization and quantum frustration, with real-world materials. My research is mainly based on well-established first-principles calculation, from which the properties of materials are simulated, quantified and further mapped to effective physical models. In some sense, we intentionally push the DFT calculation to the edge of its comfort zone, and treat it as a kaleidoscope that projects the correlated materials to a non-interacting Hilbert space. It is not a 'WYSIWYG' tool, but with some imaginations you can still infer what the reality may look like. These studies are also used to provide important support for the synthesis, characterization and modulation of materials in experiment.
