[QE-users] Zak Phase (Z2 invariant) computation

[Rameswar Bhattacharjee]

Hi Everyone,
Can anyone in this forum suggest to me how to compute the Z2 invariant
of Zak Phases to determine the nature of the topological phase?

The Z2 value can be 0 or pi but I am not sure if we can compute this in QE.

Any suggestion would be appreciated. Thanks in advance.

Thanks
