One goal of science is to find physical descriptions of nature by studying how basic system components interact with one another. For complex many-body systems, effective theories are frequently used to this end. They allow describing the interactions without having to observe a system on the smallest of scales. Physicists at Heidelberg University have now developed a new method that makes it possible to identify such theories experimentally with the aid of so-called quantum simulators. The results of the research effort, led by Prof. Dr. Markus Oberthaler (experimental physics) and Prof. Dr. Jürgen Berges (theoretical physics), were published in the journal Nature Physics.
