triqs.experimental.lattice.lattice.make_tb_hk_from_w90_tb_file()

Dispatched C++ function(s).

[1] (w90_path_and_seedname: str)
  -> TbHk

Build a tight-binding Hamiltonian from a Wannier90 *_tb.dat file.

This is a convenience wrapper that reads the file and keeps only the lattice vectors and hopping matrices, discarding the position operators and unit-cell vectors.

Parameters:

w90_path_and_seednamestr

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

Returns:

TbHk

Tight-binding Hamiltonian with hoppings in units of eV.
