- triqs.lattice.utils.parse_hopping_from_wannier90_hr_dat(filename)[source]
Parse the real-space hoppings from a Wannier90
*_hr.datfile.Returns a dictionary whose keys are the real-space hopping vectors, in multiples of the lattice vectors, and whose values are
(num_wann, num_wann)numpy arrays of hopping integrals.- Parameters:
- filenamestr
Wannier90
*_hr.datfile to parse.
- Returns:
- hopp_dictdict
Dictionary of real-space hoppings.
- num_wannint
Total number of Wannier functions per unit cell.
