A <sup>87</sup>Sr SU(10) platform in the Mott-insulating regime

ORAL

Abstract

Atomic coherence is a key quantum resource in state-of-the-art optical lattice clocks, enabling record stability via simultaneous interrogation of many atoms. Preparing insulating states of matter at high density in a shallow 3D optical lattice can realize long atomic coherence times, mitigating both tunneling induced dephasing and lattice photon scattering. The SU(10) symmetry of 87Sr provides efficient evaporative cooling to achieve a highly degenerate Fermi gas, opening the door to the realization of a well characterized, interacting system in our 3D lattice. Utilizing in situ, saturated fluorescence detection we present results studying this platform operating in the Mott-insulating regime.
