Generation of macroscopic pair-correlated atomic beams by four-wave mixing in Bose-Einstein condensates.

چکیده
By colliding two Bose-Einstein condensates, we have observed strong bosonic stimulation of the elastic scattering process. When a weak input beam was applied as a seed, it was amplified by a factor of 20. This large gain atomic four-wave mixing resulted in the generation of two macroscopically occupied pair-correlated atomic beams.

Observation of atom pairs in spontaneous four-wave mixing of two colliding Bose-Einstein condensates.
We study atom scattering from two colliding Bose-Einstein condensates using a position sensitive, time resolved, single atom detector. In analogy to quantum optics, the process can also be thought of as spontaneous, degenerate four-wave mixing of de Broglie waves. We find a clear correlation between atoms with opposite momenta, demonstrating pair production in the scattering process. We also ob...
متن کاملAtomic four-wave mixing via condensate collisions
We perform a theoretical analysis of atomic four-wave mixing via a collision of two Bose-Einstein condensates of metastable helium atoms. The analysis is based on first-principles quantum simulations using the positive P-representation method and is aimed at modeling recent experiments at Orsay [2]. Using the actual experimental parameters, we calculate atom-atom pair correlations within the s-...
متن کاملThe onset of matter-wave amplification in a superradiant Bose-Einstein condensate.
The interaction of short and strong laser pulses with an atomic Bose-Einstein condensate is found to generate patterns of recoiling atoms that are different from those seen in previous light-scattering experiments. This phenomenon can only be explained by optical stimulation, showing that the previous description of superradiance as atomic stimulation is incomplete and that matter-wave amplific...
متن کاملQuantum correlated twin atomic beams via photodissociation of a molecular Bose-Einstein condensate
The successful production of Bose-Einstein condensates ~BEC! has led to measurements indicating that BECs have coherence properties similar to lasers. This suggests that the next stage in obtaining precision measurements in atom optics is the production of atom beams with sub-Poissonian atom statistics—as has been widely demonstrated in photonics applications. Indeed, there is already some indi...
متن کاملSoliton "molecules": robust clusters of spatiotemporal optical solitons.
We show how to generate robust self-sustained clusters of soliton bullets-spatiotemporal (optical or matter-wave) solitons. The clusters carry an orbital angular momentum being supported by competing nonlinearities. The "atoms" forming the "molecule" are fully three-dimensional solitons linked via a staircaselike macroscopic phase. Recent progress in generating atomic-molecular coherent mixing ...
