triqs.experimental.lattice.lattice.read_wannier90_hr_data()

Dispatched C++ function(s).

[1] (w90_path_and_seedname: str)
  -> tuple[[[int, len = 3]], [ndarray[complex, 2]]]

Read a Wannier90 *_hr.dat file and return the lattice vectors and hopping matrices.

The file is located by appending _hr.dat to the given path and seedname. The lattice vectors \(\mathbf{R}\) are returned in crystal (lattice) coordinates and the hoppings in eV.

Parameters:

w90_path_and_seednamestr

Path to the Wannier90 files including the seedname, such that the file to read is <w90_path_and_seedname>_hr.dat.

Returns:

tuple[[[int, len = 3]], [ndarray[complex, 2]]]

Tuple containing the lattice vectors \(\mathbf{R}\) (shape [nR, 3]) and the hopping matrices (shape [nR, nOrb, nOrb]).
