论文摘要
通过光学晶格电势将Rubidium Bose-Einstein冷凝物的聚焦进行了数值研究。将结果与经典轨迹模型进行比较，该模型低估了聚焦梁的全宽度最大宽度。通过将相互作用的影响包括在Bose-Einstein冷凝物中，与Gross-Pitaevskii方程的数值整合相比，可以获得对聚焦束的全宽度最高宽度最大宽度最大宽度最大宽度的可靠估计值。最后，我们研究了聚焦的最佳方案，并发现对于强烈相互作用的玻色网凝结物聚焦20 nm可能是可能的。
The focusing of a rubidium Bose-Einstein condensate via an optical lattice potential is numerically investigated. The results are compared with a classical trajectory model which under-estimates the full width half maximum of the focused beam. Via the inclusion of the effects of interactions, in the Bose-Einstein condensate, into the classical trajectory model we show that it is possible to obtain reliable estimates for the full width half maximum of the focused beam when compared to numerical integration of the Gross-Pitaevskii equation. Finally, we investigate the optimal regimes for focusing and find that for a strongly interacting Bose-Einstein condensate focusing of order 20 nm may be possible.
