Open Postdoc Position at LU Hannover - Quantum Logic Manipulation and Detection of Single (Anti-)Protons

We are seeking a postdoctoral researcher to demonstrate quantum logic inspired manipulation of single (anti-)protons through single trapped atomic ions for precision measurements. The manipulation tools we develop follow the proposal of Heinzen and
Windeland. The necessary interaction between the (anti-)proton and the qubit-ion will be provided in a microfabricated double-well Penning trap stack. The full set of methods would make single (anti-)protons amenable to quantum logic manipulation in all
their quantized degrees of freedom. More generally, a lack of manipulation and cooling techniques is currently an important issue in antiproton based precision experiments, which this project aims to help overcome.

The ideal candidate will have a strong background in experimental work with trapped ions and experience in several of the areas of laser cooling, trapped-ion quantum logic, trap design, Penning traps and precision measurements. The position
will be based at Leibniz University Hannover, Germany, in close collaboration with the QUEST Institute for Experimental Quantum Metrology at PTB, Braunschweig, and the BASE collaboration.

Please contact Christian Ospelkaus (christian.ospelkaus@iqo.uni-hannover.de) for details.

 

Open PhD Position

BASE is a high precision Penning trap experiment, dedicated to measure the magnetic moment of the antiproton to a resolution of at least one part in a billion. This will provide one of the most stringent tests of CPT invariance. The operation of a cryogenic Penning trap experiment involves a broad range of multiple experimental techniques which are related to the design of high-precision multi-Penning trap systems, ultra low-noise electronics engineering, software development as well as mechanical engineering. Several advanced ion trap techniques have been developed in BASE, as the observation of individual (anti)proton spin quantum jumps, the application of the double Penning trap technique with a single proton, as well as the most precise measurement of the proton magnetic moment.  All required techniques are combined to investgate the fundamental laws of physics, by experiments with antimatter at lowest energies and with greatest precision.  

For detailed information please contact stefan.ulmer@cern.ch.  

The candidate will be affiliated to the Max Planck Institute for Nuclear Physic at Heidelberg, and will reveice its PhD title from the University of Heidelberg, Germany.
