Designing two-dimensional dynamical potentials using fast controllable devices — •Mareike Hetzel, Andreas Hüper, Cebrail Pür, Jiao Geng, Ilka Kruse, Jan Peise, and Carsten Klempt — Institut für Quantenoptik, Leibniz Universität Hannover

Arrays of atoms trapped by optical tweezers enable the study of phenomena in the field of quantum computing and many-body physics. The individual control of each site allows the precise quantum engineering of freely adjustable Hamiltonians. Here, we present the generation of arbitrary two-dimensional light patterns with fast dynamic control. The patterns are created by an acousto-optic deflector together with a versatile software-based radio-frequency generator. Our solution offers higher dynamic modulation speeds compared to competing system with digital micromirror devices or spatial light modulators. We present a test setup that is used to characterize the key components and demonstrate its capabilities by generating a set of optical potentials including lattice patterns, defects and dynamically generated structures. We further show a possible implementation of the setup in our experimental apparatus.
