分子解离中原子的空间对关联
Spatial pair correlations of atoms in molecular dissociation
摘要：
我们进行第一性原理量子模拟的解离捕获，空间不均匀的玻色-爱因斯坦凝聚体的分子二聚体。具体来说，我们研究了空间对的相关性的原子在飞行时间后解离。我们发现，可观察到的相关性可能会显着降低系统的空间不均匀性相比，理想化的均匀模型的预测。我们展示了如何合并的信号可以提高可检测的相关性，并导致违反经典的Cauchy-Schwartz不等式和相对数压缩。
英文摘要：
We perform first-principles quantum simulations of dissociation of trapped, spatially inhomogeneous Bose-Einstein condensates of molecular dimers. Specifically, we study spatial pair correlations of atoms produced in dissociation after time of flight. We find that the observable correlations may significantly degrade in systems with spatial inhomogeneity compared to the predictions of idealized uniform models. We show how binning of the signal can enhance the detectable correlations and lead to the violation of the classical Cauchy-Schwartz inequality and relative number squeezing.
