MAGIS-100 is a next-generation quantum sensor under construction at Fermilab that aims to explore fundamental physics with atom interferometry over 100-meter baseline. This novel detector will search for ultralight dark matter, test mechanics in new regimes, and serve as technology pathfinder future gravitational wave detectors previously unexplored frequency band. It combines techniques demonstrated state-of-the-art 10-meter-scale interferometers the latest technological advances of world's...
We report the first realization of large momentum transfer (LMT) clock atom interferometry. Using single-photon interactions on strontium ^{1}S_{0}-^{3}P_{1} transition, we demonstrate Mach-Zehnder interferometers with state-of-the-art separation up to 141 ℏk and gradiometers 81 ℏk. Moreover, circumvent excited state decay limitations extend gradiometer duration 50 times lifetime. Because broad velocity acceptance interferometry pulses, all experiments are performed laser-cooled atoms at a...
Floquet engineering offers a compelling approach for designing the time evolution of periodically driven systems. We implement periodic atom-light coupling to realize atom optics on strontium ^{1}S_{0}-^{3}P_{1} transition. These reach pulse efficiencies above 99.4% over wide range frequency offsets between light and atomic resonance, even under strong driving where this detuning is order Rabi frequency. Moreover, we use compensate differential Doppler shifts in large momentum transfer...
The ${{^1\mathrm{S}_0}\!-\!{^3\mathrm{P}_0}}$ clock transition in strontium serves as the foundation for world's best atomic clocks and gravitational wave detector concepts atom interferometry. This is weakly allowed fermionic isotope $^{87}$Sr but strongly forbidden bosonic isotopes. Here we demonstrate coherent excitation of ${}^{88}$Sr using a novel collinear three-photon process weak magnetic field. We observe Rabi oscillations with frequencies up to $50~\text{kHz}$...
Floquet engineering offers a compelling approach for designing the time evolution of periodically driven systems. We implement periodic atom-light coupling to realize atom optics on strontium ${}^1\!S_0\,\text{-}\, {}^3\!P_1$ transition. These reach pulse efficiencies above $99.4\%$ over wide range frequency offsets between light and atomic resonance, even under strong driving where this detuning is order Rabi frequency.

Floquet engineering offers a compelling approach for designing the time evolution of periodically driven systems. We implement periodic atom-light coupling to realize atom optics on strontium 1S0 – 3P1 transition. These reach pulse efficiencies above 99.4% over wide range frequency offsets between light and atomic resonance, even under strong driving where this detuning is order Rabi frequency.
