中性原子的磁静电环阱
Proposed magneto-electrostatic ring trap for neutral atoms
摘要：
提出了一种利用磁静电势将冷中性原子囚禁在微观环中的新方法。捕获势是由来自硬盘驱动器原子镜的排斥磁场和由在硬盘驱动器表面上图案化的带电盘产生的吸引势的组合导出的。我们计算了[133Cs，87Rb，40K]的陷阱频率为[29.7，42.6，62.8] kHz，陷阱深度为[16.1，21.8，21.8] MHz，并讨论了一种简单的加载方案和制作方法。该装置提供了一个一维的潜力，在一个环的几何形状，可能是感兴趣的研究被困量子简并一维气体。
英文摘要：
We propose a novel trap for confining cold neutral atoms in a microscopic ring using a magneto-electrostatic potential. The trapping potential is derived from a combination of a repulsive magnetic field from a hard drive atom mirror and the attractive potential produced by a charged disk patterned on the hard drive surface. We calculate a trap frequency of [29.7, 42.6, 62.8] kHz and a depth of [16.1, 21.8, 21.8] MHz for [133Cs, 87Rb, 40K], and discuss a simple loading scheme and a method for fabrication. This device provides a one-dimensional potential in a ring geometry that may be of interest to the study of trapped quantum degenerate one-dimensional gases.
