This means using different values for the 'salt' parameter. The actual values used for 'salt' are not important, as long as they differ; 'kwant.digest.uniform' is a hash function (see https://en.wikipedia.org/wiki/Salt_(cryptography) ). You would do something like the following: syst = kitaev(L=...).finalized() params = dict(mu=..., W=..., t=..., Delta=...) # We (arbitrarily) choose the salts as the strings '0', '1', ... salts = map(str, range(100)) for params['salt'] in salts: ham = syst.hamiltonian_submatrix(params=params, sparse=False) evals = np.linalg.eigvalsh(ham) ... Happy Kwanting, Joe
