Maximal localized wannier function

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.
