Post-doctoral fellowship on Cavity Quantum Electrodynamics:

Exploring Quantum Effects in a Strongly Coupled Atom-Cavity System

Job summary:
A single atom strongly coupled to an optical cavity is a paradigm for the study of fundamental matter-light interactions. A plethora of quantum effects has been observed in this system in recent years, such as squeezing, a two-photon-gateway, or cavity electromagnetically induced transparency (cEIT). In a new experimental setup, which is uniquely adapted for this purpose, our group will explore cEIT further, whereas the ultimate goal is to achieve switching between two light fields which are both on the single photon level.

Job description:
You will work on a cutting-edge experiment, where laser cooled atoms are captured inside a high-finesse optical resonator within an intra-cavity optical dipole trap. Advanced techniques such as cavity or feedback cooling are used and allow for a good localization of the single atom within the cavity mode so that it experiences strong coupling. Then, probe and control laser fields can be applied and a cEIT spectrum can be taken. Performing such measurements and acquiring data requires advanced experimental control techniques. Only the continuous development of customized tools adapted to our experimental needs make the observation of such fundamental quantum effects possible.

To face the everyday challenges in the laboratory, you should have or be ready to get hands-on experience with setting up optical components, designing customized optics, building ultra-low noise electronics, stabilize lasers, programming FPGAs and microprocessors, and simulating quantum optical systems. As integral part of our research team, you will be involved at all stages of the experiment, ranging from project planning over experimental implementation and data evaluation to presentation of the results on conferences and in peer-reviewed publications.

You are a talented and highly motivated researcher holding a PhD in physics with emphasis on quantum optics or atomic physics. To complement our experimental team you should have prior experience in a research laboratory. Fluency in English is mandatory; language skills in German are helpful

About MPQ:
The Max-Planck-Institute of Quantum Optics (MPQ) in Garching, 15 km north of the center of Munich, is one of the world’s top-level research centers for quantum optics. With more than 200 scientists working in five divisions on different aspects of matter-light interactions, MPQ is one of the largest centers for quantum optics research in the world. The Quantum Dynamics Division, led by Gerhard Rempe, has three operational atom-cavity systems, studying quantum gases. Other research activities of the division are cooling of polar molecules and many body physics in optical lattices.
