I am a fresh use of wannier90 package. Recently, I have used the following tags in wannier90.win file to get the Berry curvature for some system:
fermi_energy = -1.78188593kpath = true
berry_curv_unit = bohr2kpath_task = bands+curvkpath_num_points = 100Begin Kpoint_PathM 0.00000 0.50000 0.0000 G 0.00000 0.00000 0.0000G 0.00000 0.00000 0.0000 K -0.3330 0.667 0.0000K -0.3330 0.6670 0.0000 M 0.00000 0.50000 0.0000M 0.00000 0.50000 0.0000 G 0.00000 0.00000 0.0000End Kpoint_Path
After the calculation completed, I got a file with the name " wannier90-curv.dat". But now i am confused to understand this dat file. Specially i am unable to identify the high symmetry kpoints (such as G,M and K etc) in this dat file. Basically, there are four columns in the " wannier90-curv.dat" file. I think the first column represents the kpoints while the 2nd, 3rd, and 4th columns represent the berrycurvature in the X, Y, and Z-direction respectively. Can you guide me that how can i identify the high symmetry kpoints (like G,K,M) in this dat file? Your help would be highly appreciated.Thank you.
