N2 - We apply genuine multipartite concurrence to investigate entanglement properties of three Jaynes–Cummings systems. Three atoms are initially put in GHZ-like state and locally interact with three independent cavities, respectively. We present analytical concurrence expressions for various subsystems including three-atom, three-cavity and some atom-cavity mixed systems. We also examine the global system and illustrate the evolution of its concurrence. Except for the sudden death of entanglement, we find for some initial entanglement parameter θ, the concurrence of the global system may maintain unchanged in some time intervals.
