Generalized boson algebra and its entangled bipartite coherent states
Abstract
Starting with a given generalized boson algebra U<q>(h(1)) known as the bosonized version of the quantum super-Hopf Uq[osp(1/2)] algebra, we employ the Hopf duality arguments to provide the dually conjugate function algebra Fun<q>(H(1)). Both the Hopf algebras being finitely generated, we produce a closed form expression of the universal T matrix that caps the duality and generalizes the familiar exponential map relating a Lie algebra with its corresponding group. Subsequently, using an inverse Mellin transform approach, the coherent states of single-node systems subject to the U<q>(h(1)) symmetry are found to be complete with a positive-definite integration measure. Nonclassical coalgebraic structure of the U<q>(h(1)) algebra is found to generate naturally entangled coherent states in bipartite composite systems.
