Z2Pack released - a tool for computing topologic ... (No replies)
Back to General announcements...
Dear members of the Psi-k community,
it is our pleasure to announce the release of Z2Pack - a tool to calculate topological invariants for real materials. The code can identify topological phases from k.p or tight-binding models, or directly from some first principles codes. The method is based on tracking Wannier charge centers to compute Chern and Z2 invariants in different cases, and allows one to capture topological insulator (including the spatial symmetry protected ones) and semimetal phases.
A preprint describing Z2pack and its application to various systems is available at https://arxiv.org/abs/1610.08983. A comprehensive documentation for the code and its usage is available at http://z2pack.ethz.ch/doc/.
The code is released under the GPL license, and can be downloaded from the Python package index https://pypi.python.org/pypi/z2pack/ or from the GitHub repository https://github.com/Z2PackDev/Z2Pack/. Suggestions, feedback and contributions are very welcome. For questions, you can use the mailing list [email protected].
We hope that you will find Z2Pack useful for your research,
Dominik Gresch, on behalf of the Z2Pack authors
