21 Mar 2001 | Journal: | Phys. Rev. Lett. 87, 160403 (2001). | Subject: | Soft Condensed Matter; Atomic Physics; Chemical Physics | cond-mat.soft physics.atom-ph physics.chem-ph quant-ph | Abstract: | We theoretically examine photoassociation of a non-ideal Bose-Einstein condensate, focusing on evidence for a macroscopic superposition of atoms and molecules. This problem raises an interest because, rather than two states of a given object, an atom-molecule system is a seemingly impossible macroscopic superposition of different objects. Nevertheless, photoassociation enables coherent intraparticle conversion, and we thereby propose a viable scheme for creating a superposition of a macroscopic number of atoms with a macroscopic number of molecules. | Source: | arXiv, cond-mat/0103437 | Other source: | [GID 662859] pmid11690190 | Services: | Forum | Review | PDF | Favorites |
