چکیده
Recent experimental measurements of atomic intensity correlations through atom shot noise suggest that atomic quadrature phase correlations may soon be measured with a similar precision. We propose a test of local realism with mesoscopic numbers of massive particles based on such measurements. Using dissociation of a Bose-Einstein condensate of diatomic molecules into bosonic atoms, we demonstrate that strongly entangled atomic beams may be produced which possess EinsteinPodolsky-Rosen (EPR) correlations in particular field quadratures, in direct analogy to the position and momentum correlations originally considered by EPR.

متن کاملFermionic and bosonic atom correlations in molecular dissociation
Dissociation of a molecular dimer produces two quantum mechanically entangled atoms with equal and opposite momenta in the molecule’s rest frame. These atoms have Einstein-Podolsky-Rosen type correlations [1], and hence are of fundamental interest. It is possible to produce Bose-Einstein condensates (BECs) of molecules, and then to dissociate them as in Ref. [2], so that these correlations may ...

We have measured the relative phase of two Bose-Einstein condensates (BEC) using a time-domain separated-oscillatory-field condensate interferometer. A single two-photon coupling pulse prepares the double condensate system with a well-defined relative phase; at a later time, a second pulse reads out the phase difference accumulated between the two condensates. We find that the accumulated phase...

We report on a systematic treatment of Coulomb corrections for 3-and n-particle (Bose-Einstein) correlations, leading to a removal of a 100 % systematic error from earlier Coulomb corrections of 5-particle Bose-Einstein correlations in heavy ion collisions. These results are generalized to include strong final state interactions and core-halo effects.

Recent experiments with Bose-Einstein condensates of Rb atoms near a Feshbach resonance have produced evidence for a condensate of diatomic molecules coexisting with the atom condensate. It should also be possible to create condensates of the triatomic molecules predicted by Efimov coexisting with the atom and dimer condensates. The smoking gun for the trimer condensate would be oscillatory dep...
