Calculating Berry Phase around a loop

My material is 2D so the typical weyl sphere method might not be correct in my case. I'm trying to calculate the berry phase for a closed circular loop in...

Calculating Berry Phase around a loop

To illustarte further please check the below result, I cant seem to calculate the berry phase in a correct way. I chose the loop to be around K point Berry...

Calculating Berry Phase around a loop

If I understand correctly, that means if the Berry phase is pi I should expect a polarization of 0.5. ?? So is there is a way by which I can...

Calculating Berry Phase around a loop

> One way which I think could occur is that the Berry phase of each band individually goes to > 𝜋 > as the radius goes to zero. But there...

Calculating Berry Phase around a loop

Thanks for your reply > The important here would be that the individual bands have fractional polarization _as the loop radius goes to zero_. In that case, the gap cannot...
