symclosestwannier 1.9.2

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 based on the Symmetry-Adapted Multipole Basis (SAMB) [1] and the Closest Wannier formalism developed by Taisuke Ozaki [2].

• Requirements:

  • Symmetry-Adapted Multipole Basis (SAMB) for molecular or crystal are optionally generated by MultiPie.
  • MultiPie library optionally requires TeXLive environment to create LaTeX and PDF files.
  • Molecular or crystal structure files are optionally generated by QtDraw.

• To Do:

  • add function to read seedname.uHu, seedname.uIu files.
  • add SHC, ME response functions.
  • add lindhard function.
