Abstract

The sensitivity of atom interferometers depends on their ability to realize long pulse separation times and prevent loss of contrast by limiting the expansion of the atomic ensemble within the interferometer beam through matter-wave collimation. Here we investigate the impact of atomic interactions on collimation by applying a lensing protocol to a 39K Bose-Einstein condensate at different scattering lengths. Tailoring interactions, we measure energies corresponding to (340 ± 12) pK in one direction. Our results are supported by an accurate simulation, which allows us to extrapolate a 2D ballistic expansion energy of (438 ± 77) pK. Based on our findings we propose an advanced scenario, which enables 3D expansion energies below 16 pK by implementing an additional pulsed delta-kick. Our results pave the way to realize ensembles with more than 1 × 105 atoms and 3D energies in the two-digit pK range in typical dipole trap setups without the need for micro-gravity or long baseline environments. Precision measurements with atom interferometers benefit from reducing the expansion rate of the atomic ensemble within the interferometric beam through matter-wave collimation. Here we demonstrate a collimation method based on time-averaged optical potentials and tunable interactions, realizing expansion energies of a few hundred picokelvin.

利用散射长度和势能形状控制将物质波准直到皮开尔文能量
原子干涉仪的灵敏度取决于其实现长脉冲分离时间的能力,以及通过物质波准直限制干涉仪光束内原子团的膨胀以防止对比度损失的能力。在这里,我们通过对不同散射长度的 39K 玻色-爱因斯坦凝聚态应用透镜协议,研究原子相互作用对准直的影响。通过调整相互作用,我们在一个方向上测量了对应于 (340 ± 12) pK 的能量。我们的结果得到了精确模拟的支持,从而推断出二维弹道膨胀能量为 (438 ± 77) pK。根据我们的研究结果,我们提出了一种先进的方案,通过实施额外的脉冲三角踢,实现低于 16 pK 的三维膨胀能量。我们的研究结果为在典型偶极陷阱设置中实现原子数超过 1 × 105 的原子集合和两位数 pK 范围内的三维能量铺平了道路,而无需微重力或长基线环境。

期刊介绍: Communications Physics is an open access journal from Nature Research publishing high-quality research, reviews and commentary in all areas of the physical sciences. Research papers published by the journal represent significant advances bringing new insight to a specialized area of research in physics. We also aim to provide a community forum for issues of importance to all physicists, regardless of sub-discipline. The scope of the journal covers all areas of experimental, applied, fundamental, and interdisciplinary physical sciences. Primary research published in Communications Physics includes novel experimental results, new techniques or computational methods that may influence the work of others in the sub-discipline. We also consider submissions from adjacent research fields where the central advance of the study is of interest to physicists, for example material sciences, physical chemistry and technologies.
