Wannier Berri
A code for construction of Wannier functions and Wannier interpolation.
- Symmetry-adapted Wannier functions
- Symmetrization of the Hamiltonian and matrix elements
- Fast evaluation of k-space integrals
- Berry-type quantities:
- Berry curvature
- Orbital moment
- Berry curvature dipole
- Gyrotropic magnetoelectric effect
- Anomalous Hall conductivity
- Optical conductivity
- Low-field Hall effect
- eMChA
- and many more

Improved performance and accuracy
Wannier-Berri calculates Brillouin-zone integrals very fast with high precision over an ultra-dense k-grid. This is achieved by:
- Fast Fourier Transform
- Symmetry reduction to the irreducible Brillouin zone
- Recursive adaptive refinement
- Optimized Fermi-level scan
- Optimized minimal-distance replica method (
use_ws_distance)
Other features
- Object-oriented structure that makes extending features easier
- Support for tight-binding models and k·p models, not only Wannier functions
- Parallel execution via the ray module
Installation
