Ultracold Rydberg trimers — •Iris Reichenbach, Weibin Li, Jovica Stanojevic, Thomas Pohl, and Jan-Michael Rost — Max Planck Institut für Physik komplexer Systeme, Dresden, Germany

The interactions of cold Rydberg atoms are an interesting system for both basic research as well as interesting novel applications like quantum information processing and ultracold chemistry. Recently, the formation of very large and loosely bound molecules consisting of one Rydberg atom and one other atom was predicted theoretically and realized experimentally. Here, we investigate the formation of similar Rydberg molecules, where the non-Rydberg atom is substituted by a molecular dimer, leading to an even richer but still tractable system, in which the energy of the Rydberg molecule depends on the orientation of the original dimer.
