Abstract
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.

Correction: 2γ and have been replaced by and in Eq. (3) and in the paragraph below it, as well as in the caption to Figure 1 and in the paragraph above the Acknowledgment section. The previously published Figure 1 also has been replaced. Minor errors have also been fixed in Eqs. (3), (10), and (11) and in text that appears two paragraphs above Eq. (3).
