Generation of Structure under Extreme Conditions: Ultracold Atoms meet Heavy-Ion Collissions — •Jens Braun — Institut für Kernphysik, TU Darmstadt, Germany

The theory of the strong interaction describes the appearance of the fundamental building blocks of matter in the early Universe. This state of matter is currently probed in relativistic heavy-ion collision experiments, where we encounter temperatures much larger than those of any other experiment. As a complement, experiments with fermionic atoms in the nano-Kelvin regime provide a remarkably clean and versatile environment to test our understanding of a broad range of phenomena: from superconductivity and the formation of condensates to the generation of bound states in strongly coupled systems.

What do these systems have in common? As I will explain in this talk, studies of ultracold atomic gases and the theory of the strong interaction are actually similar in many ways, yet a consistent first-principles description of the experimental data remains challenging. I will present an overview of some of the most intriguing open questions on the phase diagrams of the theory of the strong interaction and ultracold gases, and discuss how an exchange of techniques between these fields is helping us to understand collective phenomena and phase transitions in strongly coupled matter in general.
