AiiDA tight-binding extraction¶
aiida-tbextraction is an AiiDA plugin for creating first-principles based Wannier tight-binding models. It defines workflows that can be used to automatically run a first-principles calculation, extract a tight-binding model using Wannier90, and perform post-processing steps such as symmetrization with TBmodels. Additionally, the energy windows used in Wannier90 can be automatically optimized, for example to achieve a better band-structure fit.
