一种稳定分子凝聚体的Feshbach激发光生
Feshbach-Stimulated Photoproduction of a Stable Molecular Condensate
摘要：
光缔合和费什巴赫共振在原理上是从已经量子简并的原子气体中产生分子玻色-爱因斯坦凝聚体的可行手段;然而，平均场位移和不可逆衰变对单独使用任一机制有效递送稳定分子施加了实际限制。因此，我们提出了Feshbach受激拉曼光产生，即，磁性和光学方法的组合，作为一种可行的手段，共同转换成一个稳定的分子凝聚体与近单位效率的简并原子。
英文摘要：
Photoassociation and the Feshbach resonance are, in principle, feasible means for creating a molecular Bose-Einstein condensate from an already-quantum-degenerate gas of atoms; however, mean-field shifts and irreversible decay place practical constraints on the efficient delivery of stable molecules using either mechanism alone. We therefore propose Feshbach-stimulated Raman photoproduction, i.e., a combination of magnetic and optical methods, as a viable means to collectively convert degenerate atoms into a stable molecular condensate with near-unit efficiency.
