A tool for computing topological invariants

Project description

Z2Pack is a tool for calculating topological invariants on first-principles (z2pack.fp) and tight-binding (z2pack.tb) systems.

It uses the method described in http://journals.aps.org/prb/abstract/10.1103/PhysRevB.83.235401 to calculate the Z2 topological invariant.

Overlap matrices are calculated either directly (for tb) or via the Wannier90 code package (fp).
