Abstract : Optical lattice systems provide an ideal platform for investigating entanglement because of their unprecedented level of flexibility and dynamical control in experiments. The goal of this research project was to utilize novel superlattice geometries where each lattice site is composed of a multiple-well potential. More specifically, the goals were: (i) Prepare and characterize various initial states of a rubidium and/or potassium system experimentally and theoretically. (ii) After an instantaneous or continuous change of the system Hamiltonian, follow the entanglement dynamics of the system using various theoretical techniques and compare to experimental measurements of correlation functions that quantify the entanglement. The studies aimed to provide deep insights into the emergence of entanglement and its connection to equilibration and thermalization mechanisms. A detailed understanding of these processes is essential for utilizing the full potential of entanglement and to refine quantum technology applications. As described in this and our progress reports, important results were obtained during the duration of the ARO grant.
