Research

The group focuses on experiments with cold atomic mixtures to study a variety on quantum problems. As the detailled description is most of the time out-of-date as soon as we write it, we provide here access to our conference posters. They should give a timely impression of the problems under investigation. Further details can be found under publications.

A few thoughts about quantum circuits and cold atoms

In this blog-post, we present our path and thoughts towards using ultra-cold atom experiments for quantum computation. They are the result of a two month internship where we studied the feasibility of such an undertaking in our group. Many associate only universal devices, especially qubit devices, to be valid quantum computers. We show how we think of our ultra-cold atoms in terms of quantum circuits and implement first steps in the software framework PennyLane.

A short (mathy) introduction to dynamical gauge fields

We wrote a blog post to give an introduction into the ideas underlying dynamical gauge fields. If you feel like it please take a look.

A short introduction to the Kondo effect

The investigation of the Kondo effects is one of the major motivations for the construction of the new experiment. 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.
