玻色-爱因斯坦凝聚体光缔合分子量子态的操纵
Manipulating Quantum States of Molecules Created via Photoassociation of Bose-Einstein Condensates
摘要：
研究了玻色-爱因斯坦凝聚体双色光缔合中的量子态转移技术，其中量子化场用于耦合原子态到激发态的自由束缚跃迁。在弱激发条件下，我们发现量子化光场的量子态可以转移到所产生的分子凝聚体中。通过考虑在当前PA实验中发现的原子和分子衰变，证实了这种技术的可行性。这些结果使我们能够操纵玻色-爱因斯坦凝聚体光缔合中分子的量子态。
英文摘要：
We show the quantum state transfer technique in two-color photoassociation (PA) of a Bose-Einstein condensate, where a quantized field is used to couple the free-bound transition from atom state to excited molecular state. Under the weak excitation condition, we find that quantum states of the quantized field can be transferred to the created molecular condensate. The feasibility of this technique is confirmed by considering the atomic and molecular decays discovered in the current PA experiments. The present results allow us to manipulate quantum states of molecules in the photoassociation of a Bose-Einstein condensate.
