Report on the construction of a new Erbium-Lithium machine — •Alexandre De Martino, Florian Kiesel, Kirill Karpov, Jonas Auch, and Christian Groß — Eberhard Karls Universität Tübingen, Physikalisches Institut, AG Groß, Auf der Morgenstelle 14, 72076 Tübingen

Fermionic gases are notoriously difficult to cool down below 10% of the Fermi temperature with usual methods. Pushing the temperature limit and producing colder gases is becoming essential for the study of strongly correlated systems. Sympathetic cooling with a classical gas as an entropy reservoir may provide a new direction to overcome the current limit.

Here we report on the ongoing development of a new Erbium-Lithium machine, whose purpose is to optimize the cooling of an ultracold Lithium gas with an Erbium reservoir. This mixture has several promising features, that have not yet been utilized for sympathetic cooling in other quantum mixtures.
