论文摘要
我们基于原子质波（几乎在整个干涉仪周期内被引导在光学晶格中的原子质波），描述了一个超紧凑型（$ \ sim 10 $ cm $^3 $物理套件）的惯性传感器。我们展示了高达8 $ \ hbar k $光子动量的大动量转移（LMT），并结合了Bragg脉冲和Bloch振荡，可扩展到大量的光子。在动量传递步骤之间，我们将原子维持在共同移动的光学晶格波导中，以便原子仅在bragg脉冲期间自由空间。我们的指导物质波方法为在动态环境中的原子惯性传感铺平了道路，在动态环境中，未经捕获的原子否则将迅速与微型腔室的壁相撞。
We describe an ultra-compact ($\sim 10$ cm$^3$ physics package) inertial sensor based on atomic matter waves that are guided within an optical lattice during almost the entire interferometer cycle. We demonstrate large momentum transfer (LMT) of up to 8$\hbar k$ photon momentum with a combination of Bragg pulses and Bloch oscillations with scalability to larger numbers of photons. Between momentum transfer steps, we maintain the atoms in a co-moving optical lattice waveguide so that the atoms are in free space only during the Bragg pulses. Our guided matter wave approach paves the way for atomic inertial sensing in dynamic environments in which untrapped atoms would otherwise quickly collide with the walls of a miniature chamber.
