We　investigate　the　nonlocality　dynamics　of　two　initially　entangled　macroscopic　fields　each　interacting　with　a　resonant　two-level　atom.　The　nonlocality　of　macroscopic　field　is　characterized　by　the　extent　to　which　the　Bell　Clauser-Horne-Shimony-Holt　(CHSH)＇s　inequality　for　continuous-variable　states　is　violated.　We　show　that　the　collapse　and　revival　of　the　Bell-nonlocality　are　similar　to　the　collapse　and　revival　of　the　atomic　population　inversion　of　the　Jaynes-Cummings　model　(JCM).　(C)　2010　Elsevier　B.V.　All　rights　reserved.
