Multipartite entanglement dynamics and transfer in a double and a triple Tavis-Cummings models

In this paper, we have investigated the dynamics and transfer of multipartite entanglement via concurrence and three-tangle in a double Tavis-Cummings Model (TCM) and a triple TCM. The results are compared with those of the double Jaynes-Cummings Model (JCM) and the triple JCM. We find that the dynamics and transfer of multipartite entanglement are dependent only on the initial entanglement type itself but not on model type for the double TCM and the triple TCM. For the triple TCM and the triple JCM we find that an entanglement of different type from the initial entanglement is created. Our work will further enrich the previous results for the JCM and the TCM.
