Dear Wannier users,
How to apply symmetry protection in Wannier 90 code? The unit cell is
LaFeAsO, the space group is 129_P4/nmm, and one unit cell contains two
equivalent Fe atoms. I use the 10 Fe 3d orbitals to get the effecitve tight
binding Hamiltionian. But I found that the chemical potentials of the five
3d orbitals from the two equivalent Fe atoms is different. For example, the
chemical potential of the dxy orbital from one Fe atom is different from that
of the orther Fe atom. Can anyone give some suggetions?
Thanks a lot !
