Cold atoms have become a major platform for quantum simulation. However, they are typically constrained to a lab environment. This motivated us at the University of Heidelberg to perform a proof-of-concept, in which we tested their compatibility with data-center environments at our project partner site, the Honda Research Institute in Offenbach. The successful realization enables us to take the next steps towards modular and mobile cold atoms set-ups that are compatible with industrial work environments.

We recently installed new water-cooled magnetic field coils. Here, I will share our experiences when making these coils and discuss the experimental challenges we faced along the way.

The Kondo effect is one of the hallmarks of condensed-matter physics. It describes the peculiar interactions between previously non-interacting Fermions, which are induced by a single spin impurity at a certain temperature. Despite (or maybe because of) its large interest as a benchmark for various theoretical frameworks, it is typically quite hard to find accessible introductions in the literature. Here, I will give a very naive interpretation of the Kondo effect and discuss its possible observation in ultracold atomic gases.

Dynamical gauge fields are a fundamental concept of high-energy physics. However, learning about them typically takes enormous amounts of time and effort. As such, they are typically a bit mystical to students (including me) of other fields of physics like condensed-matter or AMO. Here, we will give a simple introduction into some of the concepts that might allow for the quantum simulation of these theories with ultracold atomic gases.The reader should know about second quantization and the basics of quantum mechanics as the arguments are based on this formalism.
