论文摘要
我们基于环陷阱中轨道角动量的量化引入物质波干扰方案。它在没有光束拆分器的情况下运行，对外部仪表场诱导的几何阶段敏感，并允许测量原子间散射长度。我们认为，使用最先进的技术，轨道角动量干涉测量法为与冷原子和bose-Einstein冷凝物进行量子相干实验提供了多功能平台。
We introduce a matter wave interference scheme based on the quantization of orbital angular momentum in a ring trap. It operates without beam splitters, is sensitive to geometric phases induced by external gauge fields, and allows measuring interatomic scattering lengths. We argue that orbital angular momentum interferometry offers a versatile platform for quantum coherent experiments with cold atoms and Bose-Einstein condensates using state-of-the-art technology.
