Berry curvature 3D 3D
Closed paths in momentum space Two ways • An external magnetic field induces cyclotron motion along a closed orbit in q space. • An electric field causes linear variation in q. The closed path is completed when the entire Brillouin zone is “visited” by increasing values of momentum
Berry phase and (name) Hall effect • Quantum Hall effect Berry curvature
Anomalous Hall effect Berry curvature
Phonons coupled with magnetic fields Main result: The PHE depends on the Berry curvature
