我们报告的本地化的离子由一个一维的光学晶格中存在一个外加外力。离子被限制径向的射频陷阱和轴向的组合静电和光晶格势。利用分辨的拉曼边带技术，一个或多个离子沿光学晶格被冷却到平均振动数=（0.1±0.1）沿着。我们测量的平均位置的周期性驱动离子的分辨率下降到λ/40，并证明本地化到一个单一的晶格网站高达10毫秒。这开辟了新的可能性，研究多体系统与长程相互作用的周期性电位，以及摩擦的基本模型。
We report the localization of an ion by a one-dimensional optical lattice in the presence of an applied external force. The ion is confined radially by a radio frequency trap and axially by a combined electrostatic and optical-lattice potential. Using a resolved Raman sideband technique, one or several ions are cooled to a mean vibrational number =(0.1±0.1) along the optical lattice. We measure the average position of a periodically driven ion with a resolution down to λ/40, and demonstrate localization to a single lattice site for up to 10 ms. This opens new possibilities for studying many-body systems with long-range interactions in periodic potentials, as well as fundamental models of friction.
