TB_from_wannier90
(seed, path='./', extend_to_spin=False, add_local=None)[source] read wannier90 output and convert to TBLattice object
reads wannier90 real space lattice vectors from seed.wout file. reads wannier90 hoppings from seed_hr.dat file
Parameters: - seed (str) – seedname of wannier90 run, name of *_hr.dat
- path (str, default = './') – path to wannier90 output dir
- extend_to_spin (bool, default= False) – extend hopping Hamiltonian with spin indices
- add_local (numpy array , default = None) – add a local term to hopping[0,0,0] of shape Norb x Norb
Returns: TBL – triqs tight binding object
Return type: triqs TBLattice object
