Dirac Quantum Materials with Shizeng Lin

Dirac quantum materials host low energy quasiparticles governed by the Dirac equation, providing a unique bridge between high energy concepts and condensed matter realizations. Their symmetry protected band topology and electronic structure make them fertile ground for interaction driven emergent phases, ranging from integer and fractional Chern insulators to topological chiral superconductors. These states exhibit robust, topologically protected, responses that are compelling for next generation quantum and low dissipation technologies.

In this talk, I will present my group’s work on Dirac quantum materials through the lens of topology and strong correlations, organized around three interconnected themes: skyrmion physics, fractional Chern insulators, and routes to high temperature topological chiral superconductivity. I will emphasize realistic materials and materials specific modeling, enabled by the tight integration of electronic structure theory, effective models, many body calculations, quantum field theory, and close collaboration with experiments. I will also discuss how we incorporate AI to learn key features of many body wave functions, moving toward an AI accelerated discovery engine for Dirac quantum materials.
