nearest_neighbor_finder(avec, abasisvec, t_list, x_init, y_init, basis_init)

Finds the relevant nearest neighbors for a given lattice.

Parameters:

• avec (ndarray) – The lattice vectors.

• abasisvec (ndarray) – The basis vectors.

• t_list (list) – The list of hopping amplitudes in order of ascending NN.

• x_init (float) – The initial x-coordinate.

• y_init (float) – The initial y-coordinate.

• basis_init (int) – The initial sublattice index.

Returns:

• data (ndarray) – The array of relevant nearest neighbors.

• bases (list) – The list of unique sublattice indices.
