解离伸长分子凝聚体的定向空间结构
Directional spatial structure of dissociated elongated molecular condensates
摘要：
二聚分子的超冷云可以分解成量子力学相关的组成原子，它们要么是玻色子，要么是费米子。我们从理论上模拟了雪茄形分子凝聚体的解离，这种差异表现为解离原子的互补几何结构。对于原子玻色子，光束沿着分子凝聚体的长轴形成。对于原子费米子来说，光束沿着短轴形成。这种定向光束通过相对数压缩简化了原子之间相关性的测量。
英文摘要：
Ultra-cold clouds of dimeric molecules can dissociate into quantum mechanically correlated constituent atoms that are either bosons or fermions. We theoretically model the dissociation of cigar shaped molecular condensates, for which this difference manifests as complementary geometric structures of the dissociated atoms. For atomic bosons beams form along the long axis of the molecular condensate. For atomic fermions beams form along the short axis. This directional beaming simplifies the measurement of correlations between the atoms through relative number squeezing.
