tbplas.gen_kdist

tbplas.gen_kdist(lattice_vectors: ndarray, kpoints: ndarray) → ndarray

Convert k_path generated by gen_path into distances in reciprocal space.

Parameters:

• lattice_vectors – (3, 3) float64 array Cartesian coordinates of lattice vectors

• kpoints – (nk, 3) float64 array fractional coordinates of kpoints

Returns:

(nk,) float64 array distance in reciprocal space in unit of reciprocal lattice vectors
