Topological materials

Searching for new topological materials, with robust electron states ideal for physical applications requires a combined understanding of solid state chemistry, physics, and group theory. We adopt an interdisciplinary approach to find common threads between available materials and understand the mechanisms that bring about nontrivial topology in nature.
