Web25 apr. 2024 · The Wannier and Bloch states satisfy the uncertainty principle in the form Δ h · Δ x ≅ 1. This means that, for rather long antenna (large Δ x), the main support to the wave-function is defined by a small region near the band minimum at the zone center. As a result, we obtain the approximate presentation for the wave function at the given zone WebIf your Wannier functions are the maximal localized ones, then this feature doesn’t work. I suggest you using Wannier90 to get spin-texture which needs information from the first …

The Wannier functions are a complete set of orthogonal functions used in solid-state physics. They were introduced by Gregory Wannier in 1937. Wannier functions are the localized molecular orbitals of crystalline systems. The Wannier functions for different lattice sites in a crystal are orthogonal, allowing a convenient basis for the expansion of electron states in certain regimes. Wannier functions have found wide… Weblocalized Wannier functions without further minimization, and it can be applied straightforwardly to random potentials without using supercells.
