An experiment to study small Fermi-Hubbard systems — Martin Schlederer, •Alexandra Mozdzen, Phillip Wieburg, Thomas Lompe, and Henning Moritz — Institut für Laserphysik, Universität Hamburg, Hamburg, Deutschland

We report on an experiment designed to create small Hubbard systems site by site.

The apparatus contains two microscope objectives located inside the vacuum chamber featuring a numerical aperture of 0.75, enabling us to load single 40K atoms into individual optical tweezers and flexible tweezer arrays. This bottom-up approach will allow us to observe the emergence of many-body effects with increasing system size or particle number. We will discuss the current status of the project.
