Hulet has also performed pioneering experiments with degenerate Fermi gases. He achieved the first observation of a polarized degenerate Fermi gas, realized a degenerate Bose-Fermi mixture, and studied spin-imbalanced Fermi gases, including a possible realization of the FFLO state in a 1D system. His group has investigated fermions in optical lattices as a model of systems of solid-state physics, and observed short-range antiferromagnetism in a Hubbard system, similar to physics also observed in the cuprate high-temperature superconductors.
