波导型原子陀螺仪有望成为下一代惯性导航系统的核心器件。光滑且低噪声的单模原子波导是实现波导型陀螺仪的关键。本项目中我们将设计和制作芯片上的单模原子波导，并利用超冷原子和玻色-爱因斯坦凝聚体研究其特性。我们将制备碳纳米管-铜复合材料，并用这种高性能导体在芯片上构建原子波导。同时我们还将试验用永磁薄膜材料在芯片上集成原子波导。通过将超冷原子和玻色-爱因斯坦凝聚体装载到原子波导里，测量其径向阱频率、势场纹波和原子在其中的寿命，然后尝试在波导里进行原子干涉实验。我们的目标是获得可用于原子干涉仪的波导，为实现波导型陀螺仪奠定基础。

Guided atomic gyroscope is a promising candidate as a core device for the next generation of inertial navigation systems. A smooth and low-noise single mode atomic waveguide is the key to the realization of guided atom gyroscopes. In this project, we plan to design and fabricate single mode atomic waveguides on chips and investigate their characteristics by using ultracold atoms and Bose-Einstein condensates. We will prepare a carbon nanotube-copper composite and use this kind of high-performance electrical conductor to build atomic waveguides on chips. We will also try to fabricate atomic waveguides on chips with permanent magnetic films. By loading ultracold atoms and Bose-Einstein condensates into atomic waveguides, we will measure their radial trap frequencies and potential corrugations and the lifetime of atoms in them. Then we will attempt to implement atom interference experiments in atomic waveguides. We aim to obtain a waveguide can be used in atomic interferometry and establish foundation to realize guided atom gyroscope.
