Reduced Wannier Representation for Topological Bands (arXiv:2412.17084)

Code for the paper "Reduced Wannier Representation for Topological Bands" by Trey Cole and David Vanderbilt.

The LaTeX source code and a pdf of the arXiv manuscript can be found in the paper folder. Results are generated using the notebooks and scripts found in the calculations folder. The .py scripts are used for enhanced performance on more lengthy calculations, and the resulting figures are generated with the notebooks of the same name. The following packages are dependencies for running the code:

• pythtb
• wanpy

The wanpy package adds functionality for computing maximally localized Wannier functions in pythtb, but has not yet been included in a release. The version for wanpy corresponding to this paper is linked as a submodule in this repository's root directory, or the most recent version can be found at the wanpy repository's main page here.

The dataset for the figures used in the paper is hosted on Zenodo with DOI 10.5281/zenodo.14544685.
