Dear Wannier90 users and developers, Recently I did a Wannier90 calculation for the 2D material under the applied electric field along z-direction using atom centered Wannier function (WF) to interpolate the DFT band structure correctly. I observe some of the WFs shifted from the initial position and have a larger spread. The total spread of WFs is nearly double with respect to without electric field calculation. I have some queries related to this topic.
1. Can the center of Wannier function shift under the electric field? 2. Is it possible to fix the center of Wannier function in Wannier90 calculations? Sincerely, Chandan Singh PhD Student Department of Physics IISER Pune, India
