The Digital Micromirror Device for the creation of arbitrary optical potentials in ultracold quantum gas experiments — •Louisa Marie Kienesberger, Alexander Guthmann, Felix Lang, Krishnan Sundararajan, and Artur Widera — Physics Department and Research Center OPTIMAS, University of Kaiserslautern-Landau, Germany

The Digital Micromirror Device (DMD) enables the creation of arbitrary optical potentials by dynamically controlling an array of micromirrors, which direct light to form desired intensity patterns. This provides a powerful tool for the precise manipulation of ultracold quantum gases. A modular design of a DMD setup is presented for a seamingless integration into the already existing experimental apparatus in our research group. Additionally, custom software was developed to control the DMD, including an active feedback loop for the stabilization of the optical potential. This system facilitates the study of diverse quantum phenomena, such as homogeneous systems using box potentials, superfluid dynamics in ring geometries, and Anderson localization in disordered potentials.
