    Controlling atom transport in a two-dimensional state-dependent optical lattice, (2017), Master thesisBibTeXPDF
    ABSTRACT »

    This thesis describes the development of an optical phase lock loop on a digital platform, in order to realize state-dependent transport on a two-dimensional optical lattice. The digital platform consists of a field programmable gate array in combination of a vector generator module, which is used to steer the amplitude and phase of the optical lattice deterministically. The digital system enables the implementation of a feedforward control scheme based on internal model control, which overcomes the bandwidth limitations of feedback systems. The control bandwidth is shown to be increased by more than an order of magnitude, directly improving the number of coherent operations that can be executed with the atoms in the optical lattice. The system is implemented into the optical setup of the experimental apparatus, and the first signatures of state-dependent transport of atoms in the two-dimensional optical lattice is observed and presented.
