title: Creating macroscopic atomic Einstein-Podolsky-Rosen states from Bose-Einstein condensates.
abstract: We present a scheme for creating quant entangled atomic states through the coherent spin-exchange collision of a spinor Bose-Einstein condensate. The state generated possesses macroscopic Einstein-Podolsky-Rosen correlation and the fluctuation in one of its quasispin components vanishes. We show that an elongated condensate with large aspect ratio is most suitable for creating such a state.
