Z2-support-OpenMX

This page supports to use our code, "Z2FH" in OpenMX 3.9. Z2FH computes $Z_{2}$ invariant by Berry curvature $F$ and Berry connection ${\bf A}$ [1,2]. This code is included in OpenMX3.9's source. It can compute the system broken space inversion symmetry, so this is suitable for computing $Z_{2}$ invariant of the system in the electric field or polar materials etc. Please cite the following article:
