    "abstract": "Recently, it has been realized that nonlocal disentanglement may take a\nfinite time as opposite to the asymptotic decay of local coherences. We find in\nthis paper that a sudden irreversible death of entanglement takes place in a\ntwo atom optical Stern-Gerlach model. In particular, the one degree non\ndissipative environment here considered suddenly destroys the initial\nentanglement of any Bell\u0027s states $\\ket{\\phi^{\\pm}}$ superposition.",
