<p>Hi Mahmood,</p>
<p><br>
</p>
<p>There is a package implemented for calculating Z2 invariant. As
far as I understand it works only for centrosymmetric systems. <br>

<div dir="auto">Hi,
<div dir="auto">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.</div>
