研究了超冷原子在抛物势和周期势联合作用下的定域性和可寻址性。这样一个潜在的支持本地化的稳定状态的存在，我们表明，应用射频场使我们能够选择性地解决这些国家的原子。这种方法用于测量局域态原子的能量和动量分布。我们还讨论了可能的扩展，这个计划，以解决和操纵原子在单一的晶格网站。
We study the localization and addressability of ultracold atoms in a combined parabolic and periodic potential. Such a potential supports the existence of localized stationary states and we show that applying a radio frequency field allows us to selectively address atoms in these states. This method is used to measure the energy and momentum distribution of the atoms in the localized states. We also discuss possible extensions of this scheme to address and manipulate atoms in single lattice sites.
