Z2Pack


is a tool for calculating topological invariants. The method is based on tracking the evolution of hybrid Wannier functions, which is equivalent to the computation of the Wilson loop. Originally developed for calculating \mathbb{Z}_2 invariants, it is now also capable of calculating Chern numbers. Moreover, through the use of individual Chern numbers it can be used to identify any kind of topological phase.

A key feature of Z2Pack is its flexibility: It can be used with various kinds of calculations and models. Currently, interfaces to first-principles codes, tight-binding models and \mathbf{k \cdot p} models are implemented. However, it can in principle be extended to any kind of system.

This is the second major release of Z2Pack. Read :ref:`here<z2pack_tutorial_new>` what's new, and find out which version is best for you.
