Interferometer for force measurement by shortcut-to-adiabatic arms guiding
arXiv:2003.04778 · doi:10.1103/PhysRevResearch.2.023328
Abstract
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.
