Abstract:
We have introduced a new class of multipartite entangled mixed states with pure state decompositions of generalized W states, similar to SC states having generalized GHZ states in the pure state decomposition. The entanglement and separability properties are studied according to PPT operations. Monogamy relations related to these states are also investigated.
