Geometry and topology in electronic structure theory - lecture 2



  • Quantum geometry (a.k.a. Berryology): connection, curvature, metric, Berry phase, Chern number.
  • Berryology in band structure.
  • Synopsis of the geometrical observables, partitioned in two classes: Observables defined modulo 2π (in dimensionless units), and observables exempt from 2π ambiguity.
