We present results of simulations highlighting the performance of a cooling mechanism in a magnetic trap tailored for excited Rydberg atoms (or molecules) with high magnetic moment. Unlike previous work, the cooling is achieved through fast stimulated decay of inter-manifold transitions which optimizes the scheme. This mechanism is relevant to experiments with trapped antihydrogen atoms for which the trapping fraction is currently low. We find several-fold enhancements of the number of atoms trapped in the configurations probed.

模拟中性原子陷阱中的反氢去激发以改善捕获和冷却

我们展示了模拟结果,强调了为具有高磁矩的激发里德伯原子(或分子)量身定制的磁阱中冷却机制的性能。与以前的工作不同,冷却是通过流形间转换的快速受激衰减实现的,从而优化了方案。这种机制与捕获反氢原子的实验有关,目前捕获分数很低。我们发现被探测配置中捕获的原子数量增加了数倍。
