Dear Vahid,
In Wannier90 you can study Berry curvature slice-by-slice using the
kslice module (see user guide)
Also, more ways of tabulating Berry curvature can be found in the
wannierberri package

Best,
Stepan.

Dear Wannier90 Users,
When the Berry curvature of a given material does not show a peak along
high-symmetry lines of the band structure, finding the coordinates in the BZ
for which the curvature is the largest is a time-consuming task. Is there a
tool that allows the user to calculate Berry curvature in 3D and then from the
visualization, deduce the coordinates of the hotspots?
Thank you,
Vahid
