Unraveling materials Berry curvature and Chern numbers from real-time evolution of Bloch states
Materials can be classified by the topological character of their electronic structure and, in this perspective, global attributes immune to local deformations have been discussed in terms of Berry curvature and Chern numbers. Except for instructional simple models, linear response theories have bee...
