In the band method, the k-dispersion is taken in account, resulting in complex wave
functions in general, while in the cluster method, only the gamma point is considered,
resulting in the real wave function if the spin-orbit coupling is ignored.
By considering those facts, relevant codes are implemented so that the required memory
can be minimized and the computation speed can be accelerated.
