symclosestwannier 2.0.6

A Python library for Symmetry-Adapted Closest Wannier (SymCW) Tight-Binding model based on Plane-Wave DFT calculation.

SymClosestWannier

• Overview: A Python library to create Symmetry-adapted Closest Wannier (SymCW) tight-binding models [1] based on the Symmetry-Adapted Multipole Basis (SAMB) [2] and the Closest Wannier formalism developed by Taisuke Ozaki [3].
