Research fellow / PhD position in experimental physics on accurate BEC interferometry for geodesy (m/w/d)

Research at the Institute of Quantum Optics focuses on highly controlled interaction of light and matter. Similar to the development of lasers for interferometry in optics, employing Bose-Einstein condensates (BECs) promises a paradigm shift in atom interferometry.
In our research group we are investigating this next generation of atom interferometers and have already set important milestones that promise higher long-term stability and a worldwide unique high accuracy for acceleration measurements. In particular, the miniaturisation into our novel transportable quantum gravimeter was an important step forward.

Activities and responsibilities

As part of the scientific activities, experimental sequences for various interferometer geometries are to be developed and measurement campaigns carried out in cooperation with the Institute of Geodesy at Leibniz Universität Hannover at geodetically relevant locations. New methods and the physics of the quantum gravimeter will be investigated, e.g. the influence of the inner-atomic collisions of a BEC and the effect of blackbody radiation on the measuring principle.

Qualification profile

A completed scientific university degree in physics or equivalent related disciplines is a prerequisite for the application. Good knowledge of atom and quantum optics is recommended and excellent academic performance is expected. Experience in laser physics, electronics, programming, and/or gravitational physics is helpful, but not mandatory.


Based on the QUEST Leibniz Research School and the current QuantumFrontiers Cluster of Excellence, we offer outstanding research opportunities with a variety of national and international collaborations.

As an equal opportunities employer, Leibniz University Hannover intends to promote women and men. For this reason, suitably qualified women are specifically invited to apply. Preference will be given to equally qualified applicants with disabilities.
