The discovery of topological materials has revolutionized our understanding of the fundamentals of solids. These materials (including topological insulators/semimetals/superconductors) are characterized by special topological invariants in their energy spectrum, and on their surfaces there are topological boundary states which can carry currents with low dissipation. They may have promising applications in quantum electronics. The study of topological materials is at the frontier of current research in multiple disciplines including physics, chemistry, and material science.
In this project, we will use first-principles computational techniques (based on the density functional theory) to explore realistic topological materials. Meanwhile, we will also use theoretical methods (such as symmetry analysis, tight-binding modeling, etc.) to explore their fascinating physical properties.
