[QE-users] Z2 topological invariant

[Asad Mahmood]

Hi,
I am working with some 2D material and putting biaxial strain in it. At
some particular value of lattice constant the band structure shows band
inversion at Gamma point. I want to calculate Z2 topological invariant.
Please help me in computing it.

Thanks,
