parse_hopping_from_wannier90_hr_dat
(filename)[source] Wannier90 real space hopping parser of
*_hr.dat
files.Returns a dictionary where the keys are the real-space hopping vectors, in terms of multiples of the lattice vectors, and the values are
num_wann * num_wann
numpy ndarrays with the hopping integrals.Parameters: filename (str) – Wannier90 *_hr.dat
file to parse.Returns: - hopp_dict (dict) – Dictionary of real space hoppings.
- num_wann (int) – Total number of Wannier functions per unit-cell.
