http://www.nanolab.ece.ufl.edu/document/Using_Wannier90.pdf 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)

WebJun 17, 2024 · Wannier Jun 17, 2024 Background Spin texture describes the pattern which k-dependent spin directions formed in the Brillouin zone. This peculiar phenomena arises from the coupling between spin and orbital motions of electrons – spin-orbital coupling (SOC).
