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