WebIn this tutorial, we will learn how to obtain Wannier functions (WFs) for PbTiO3, one of the famous insulating ferroelectric materials. In general, the procedure consists of three steps: Converging the charge density and analyzing the electronic structure (from FLEUR) Preparing the files necessary for WANNIER90 (from FLEUR) WebHere are four criterions of high-quality WFs. 1. Perfect fitting to the DFT bands in the energy range you are interested in. 2. Keep the atomic orbital symmetry. 3. Well localized. 4. As small number of WFs as possible. There are three important steps to reach four criterions. 1. Choose projectors. 2. Choose disentanglement energy window. 3.
WebWannier functions (WFs) can be obtained from Bloch states by means of the formulas 1-3 of [Souza2002a] . As you may note there is a freedom of choice in the Bloch orbital’s phase which is reflected in the shape and the spatial extent of the WF. This means that for different phases there will be WFs with different spatial localizations. WebDec 8, 2011 · Wannier-based calculation of the orbital magnetization in crystals.
