Wannier functions from Bloch orbitals in solids

WebBesides Bloch orbitals, Wannier orbitals [76] are also widely used in solid state physics. They are defined as Fourier transformations of the Bloch orbitals, e.g. [Pg.131] Figure 8 displays the maximally localized Wannier orbitals computed for one isolated water molecule. 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). crystal minecraft png

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.
