Quantum gas microscopy of three-flavor Hubbard systems

Hubbard systems are paradigmatic realizations of strongly correlated many-body systems. Introducing additional species breaks the SU(2) symmetry of the Hubbard model and leads to a wide variety of new exotic quantum phases. Here, we extended quantum gas microscopy to three-flavor Fermi lattice gases in the Hubbard regime. Relying on site- and flavor-resolved detection, we studied the phase diagram of the three-flavor Hubbard model and found signatures of flavor-selective localization and selective pairing at temperatures down to the tunneling energy scale. Our measurements were then compared with numerical linked-cluster expansion calculations. Further increase of phase space density may enable the observation of a distinct pair Mott phase at half filling and shows a path toward the study of color superfluidity and other aspects of quantum chromodynamics.
