Abstract:
The goal of this research program is to investigate strongly-correlated many-body phases that emerge when interacting fermions occupy the p-orbital band of an optical lattice. Progress made toward this objective included demonstration of a site-resolved, continuously deformable two-dimensional honeycombtriangular lattice and loading of Li-6 atoms into a triangular configuration of lattice beams. Further, a novel solid state laser source for 671 nm light was developed and new methods for rapidly controlling interactions between fermionic Li-6 atoms were demonstrated. While making this progress, scientific opportunities arose to make discoveries in other research areas of interest to the AFOSR. Specifically, the scope of the project was broadened to include studies of s-wave collisional frequency shifts in an ultracold Fermi gas relevant for improvingcharacterizing the accuracy of next generation atomic clocks, the realization of momentum dependent s-wave interactions in a Fermi gas relevant for quantum simulation, and the realization of multi-partite entangled states by dissipative exothermic collisions in a one-dimensional Fermi gas relevant for quantum metrology.
