• Basic tutorial: Interpolating bands, Berry curvatures, and integrating them
  • Preparation of a calculation:
  • Reading the system
  • Interpolation on a path
  • Running a calculation: calculators and results
  • Tabulating Berry curvature and spin
    • Running a calculation
    • Plotting the results
    • Problem 1:
    • Get the data and do whatever you want
  • Calaculation on a 3D grid
    • We can use the same tabulators, but now we pack them into TabulatorAll in “grid” mode
    • And we run the calculation in the same way
    • Analyze the tabulated data
    • Problem 2 :
    • fill the missing parts and evaluate the Berry curvature summed over all states below EF = 12.6 eV. Plot in on a plane k3=const (in reduced coordinates)
  • Integration on a grid: anomalous Hall conductivity
    • Problem 3 :
  • Tetrahedron method
  • Optical conductivity
  • All in one
