Exploring interactions in the band insulating regime with Fermi-degenerate <sup>87</sup>Sr

POSTER

Abstract

Leveraging the SU(10) symmetric ground state of 87Sr for efficient evaporative cooling, we use a stark-shift-enabled spin selection technique to load a low-entropy, spin polarized gas into a 3D optical lattice. Using high intensity, in situ fluorescence detection we present results characterizing the 3D density distribution and filling fraction in the band insulating regime of our 3D lattice. This low-entropy, band insulator provides a unique optical lattice clock system for studying atomic coherence times, spin-orbit coupling, and dipolar interactions between atoms. We will present the latest progress on this clock platform. Additionally, experimental results demonstrating Pauli blocking in our Fermi-degenerate gas will be presented.
