| Abstract: | In the framework of the U
q
(su(2)) quantum algebra, we
investigate the entanglement properties of two-spin systems, of
arbitrary spins j
1 and j
2, defined in an entanglement of
deformed spin coherent states of each of the spins. We derive the
amount of entanglement and we give conditions under which bipartite
entangled states become maximally entangled. Using these conditions,
we construct a large class of Bell states for any choices of the
parameters that specify the spin coherent states. |
