A general workflow to get unconventional insulators

Ref: Gao, J. et al. "Unconventional materials: the mismatch between electronic charge centers and atomic positions", Sci. Bull. 67 (6), 598-608 (2021).

1) prepare your POSCAR file.

2) phonopy --symmetry --tolerance 0.01 -c POSCAR

3) POS2ABR > ABR.out (converting PPOSCAR to POSCAR_std and generating ABRs)
     (* paste PPOSCAR below or download the source code *)



4) cp POSCAR_std POSCAR; do VASP/QE calculations.

5) IRVSP -sg $sgn [ -nb $m $n ] > outir (generating tqc.txt/tqc.data when using only maximal HSKPs)

6) solve EBR and ABR decompositions (using tqc.data and PPOSCAR).

     (* paste tqc.data below *)

    Note: please fill in both boxes above!
