中性原子的AC电俘获

AC electric trapping of neutral atoms

Sophie Schlunk, Adela Marian, Wieland Schoellkopf, Gerard Meijer

摘要:

研究了超冷中性原子在宏观交流电阱中的动力学行为。这种陷阱的限制是通过在电场的两个鞍点配置之间切换来实现的。逐渐形成一个稳定的陷阱云观察和陷阱的性能进行了研究与开关频率和开关周期的对称性。此外,通过对原子云的成像,绘制出阱中的电场。最后,通过引入一个改进的开关周期,探讨了阱的相空间接受度。使用完整的三维轨迹计算再现的实验结果。

英文摘要:

We study the dynamic behavior of ultracold neutral atoms in a macroscopic ac electric trap. Confinement in such a trap is achieved by switching between two saddle-point configurations of the electric field. The gradual formation of a stably trapped cloud is observed and the trap performance is studied versus the switching frequency and the symmetry of the switching cycle. Additionally, the electric field in the trap is mapped out by imaging the atom cloud while the fields are still on. Finally, the phase-space acceptance of the trap is probed by introducing a modified switching cycle. The experimental results are reproduced using full three-dimensional trajectory calculations.
