报告摘要：The derivatives of the Berry curvature and intrinsic orbital magneticmoment in momentum space are relevant to various problems, including thenonlinear anomalous Hall effect and magnetotransport (electrical magnetochiralanisotropy).To investigate these properties using first-principles methods,we have developed aWannier interpolation scheme that evaluates the"covariant derivatives" of the non-Abelian Berry curvature and orbital magnetic moment matrices for a group of bandswithin a specific energy range of interest. The developed methodology is madeavailable via the open-source code WannierBerri, and we demonstrate the efficiencyof this method through first-principles calculations on many phenomena in variousreal materials.
