Quantum Gas Microscope for Fermionic $^{\mathrm{40}}$K

In this poster, we present the recent experimental progress on our quantum gas microscope for fermionic $^{\mathrm{40}}$K. We show our findings on in-situ studies of metallic, Mott insulating, and band insulating states of the two- dimensional (2D) Fermi-Hubbard model as well as the extension of these studies to explore spatial charge and spin correlations using spin-sensitive fluorescence imaging of ultracold 40 K atoms trapped in a square optical lattice. Subsequently, we report on furthering these studies of spatial correlations to lower temperatures.
