In the Big Bang 13.8 billion years ago, equal amounts of matter and antimatter were probably created. Today, ordinary matter dominates the observable universe by many orders of magnitude. This imbalance can be explained by differences between the properties of matter and antimatter, or their interaction.

In order to elucidate this problem, two classes of experiments with antihydrogen are planned for the coming years: on the one hand laser-spectroscopic measurements, and on the other hand tests of its gravitational interaction. Our group is part of the AEGIS antimatter gravity experiment, whose construction at the Antiproton Decelerator (AD) at the European Laboratory for Particle Physics CERN is nearing completion. One of the major challenges on the path towards precision experiments is the issue of producing the coldest possible anti-atoms with a view to their confinement.


In order to produce ultracold antihydrogen, our group in Heidelberg is developing a novel method for the cooling of negative ions. For this purpose, anions will be laser-cooled in a trap for the first time world-wide. In a second step, these ions can cool antiprotons (or any other negative ions) to extremely low temperatures by collisions in the trap. This project builds on earlier work carried out at the MPI for Nuclear Physics since 2006 with funding by the German Research Foundation (DFG) and the European Research Council (ERC).


In the course of this Ph.D. project, the student will have the opportunity to acquire and apply a wide range of experimental methods of atomic physics in an excellent research environment. The project is embedded in international collaborations with research institutes in other other European countries. This will allow for the possibility of scientific exchange and stays abroad, for instance at CERN in Geneva.
