DOI: 10.1103/physreva.96.023618
Abstract: The wave-front aberration of Raman beams induces phase noise in atom interferometers and thus limits the performance of atom interferometers. We theoretically analyze the wave-front-aberration phase noise in weakequivalence-principle tests using dual-species atom interferometers, and… read more here.
