论文摘要
我们提出了一个紧凑的原子干涉仪，以测量通过捷径向绝热路径引导手臂的均匀恒定力。对于给定的灵敏度，仅取决于引导路径的时空区域，可以在不失去可见性的情况下快速制定周期时间。原子是由自旋依赖性的捕获势驱动的，朝相反的方向移动，并由线性和时间依赖的电位补充，以补偿陷阱加速度。因此，手臂状态在移动框架中是绝热的，在实验室框架中是非绝热的。诱捕电位可能是无谐的，例如光学晶格和干涉阶段不取决于最初的运动状态或旋转线性电势的枢轴点。
We propose a compact atom interferometer to measure homogeneous constant forces guiding the arms via shortcuts to adiabatic paths. For a given sensitivity, which only depends on the space-time area of the guiding paths, the cycle time can be made fast without loosing visibility. The atom is driven by spin-dependent trapping potentials moving in opposite directions, complemented by linear and time-dependent potentials that compensate the trap acceleration. Thus the arm states are adiabatic in the moving frames, and non-adiabatic in the laboratory frame. The trapping potentials may be anharmonic, e.g. optical lattices, and the interferometric phase does not depend on the initial motional state or on the pivot point for swaying the linear potentials.
