Description:
Boson realizations map operators and states of groups to transformations and states of bosonic systems. We devise a graph-theoretic algorithm to construct the boson realizations of the canonical SU( n ) basis states, which reduce the canonical subgroup chain, for arbitrary n . The boson realizations are employed to construct -functions, which are the matrix elements of arbitrary irreducible representations, of SU( n ) in the canonical basis. We demonstrate that our -function algorithm offers significant advantage over the two competing procedures, namely, factorization and exponentiation. D D
