Guided atom gyroscope on an atom chip with symmetrical state-dependent microwave potentials

Hui Yan

We proposed to realize area-enclosed Raman-type atom interferometer on an atom chip based on the moving guide. Symmetrical state-dependent microwave potentials are applied to split and recombine the atoms with different internal states along the free-propagation direction of a magnetic guide, while the atoms are translated along another direction with the moving guide back and forth. For the long coherence time of the atom internal states and the moving guide scheme, compact and large area-enclosed atom gyroscope can be realized on an atom chip.

Optically guided atom interferometer tuned to magic wavelength

Tomoya Akatsuka, Tadahiro TAKAHASHI, Hidetoshi Katori

We demonstrate an atom interferometer operating on the 1 S 0 – 3 P 0 clock transition of 87 Sr atoms in a "magic" optical guide, where the light shift perturbations of the guiding potential are canceled. As a proof-of-principle demonstration, a Mach–Zehnder interferometer is set horizontally to map the acceleration introduced by the focused optical guide. This magic guide interferometer on the clock transition is applicable to atomic elements where magic wavelengths can be found. Possible applications of the magic guide interferometer, including a hollow-core fiber interferometer and gradiometer, are discussed.
