 Since the coupling involves two spins, it is instinctive to use a two-dimensional array for ''j''. However, in a more general view, it is clearer to serialize the iteration into one over links instead of two nodes. This also reduces redundancy. Since the coupling involves two spins, it is instinctive to use a two-dimensional array for ''j''.
