Unraveling materials Berry curvature and Chern numbers from real-time evolution of Bloch states
(Natlacad Sciences, 2019-03-05)
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 ...
Orbital magneto-optical response of periodic insulators from first principles
Magneto-optical response, i.e. optical response in the presence of a magnetic field, is commonly used for characterization of materials and in optical communications. However, quantum mechanical description of electric and ...
