Upgrades for the modular quantum gas platform — •Tim Schiffer, Tobias Hammel, Daniel Dux, Finn Lubenau, Maximilian Kaiser, Matthias Weidemüller, and Selim Jochim — Physikalisches Institut, Heidelberg, Germany

The Heidelberg Quantum Architecture [1] is a modular quantum gas platform, consisting of disentangled modules forming a versatile cold atom experiment.

Here, optical units allow flexible trap geometries, fast reconfiguration and precise mechanical alignment, enabling straightforward adaptation to evolving experimental requirements in our Lithium-6 experiment.

On this poster, we report on the progress made implementing self-aligning modules and modules with increased stability. We discuss the already implemented experimental toolbox, containing optical tweezers, repulsive potentials shaped by a DMD and single-atom and spin-resolved imaging.
