论文摘要
已经研究了原子干涉仪作为一种有前途的设备，用于精确感应外场。在各种配置中，具有蝴蝶形几何形状的特定配置旨在敏感探测现场梯度。我们通过将磁场纳入传统的蝴蝶形构型中，引入了一个胸骨的蝴蝶干涉仪。可以通过控制磁场以提高干涉仪的灵敏度来灵活调节干涉仪的原子轨迹，而使用拉曼过渡的常规蝴蝶干涉仪可以理解为特殊情况。我们还表明，SG干涉仪可以与田间梯度引起的位置和动量的未对准保持较高的对比度。
Atomic interferometers have been studied as a promising device for precise sensing of external fields. Among various configurations, a particular configuration with a butterfly-shaped geometry has been designed to sensitively probe field gradients. We introduce a Stern-Gerlach (SG) butterfly interferometer by incorporating magnetic field in the conventional butterfly-shaped configuration. Atomic trajectories of the interferometer can be flexibly adjusted by controlling magnetic fields to increase the sensitivity of the interferometer, while the conventional butterfly interferometer using Raman transitions can be understood as a special case. We also show that the SG interferometer can keep high contrast against a misalignment in position and momentum caused by the field gradient.
