in the bose-hubbard model, we need to enumerate all the possible basis
usually, the basis vectors are taken as the fock states
The problem is that, how to arrange the basis and how to establish the matrix of the hamiltonian as soon as possible
It is apparent the the matrix will be very sparse
then how can we avoid to set the matrix elements that are surely zero ?
i find this problem non-trivial
