Anomalous Zeno effect for sharply localised atomic states

Abstract: We analyse non-quadratic in time Zeno effect which arises when a few-atomstate initially trapped between two high laser-induced barriers is brieflyreleased to free evolution. We identify the Zeno time, analyse the energydistributions of those atoms which have escaped an remained inside the trap,and obtain a simple relation between the survival and non-escape p..
