The RING project in Germany: 1 Postdoc and 14 PhD positions in Physics, Geophysics, Geodesy

we would like to draw your attention to the 4-year RING project recently funded by the German Research Foundation (extendable to 8 years). The project has strong overlap with gravitational wave detection research on instrumentation.

The project aims at pushing the sensitivity and stability limits of rotational motion sensing with ring laser technology into new realms using approaches from quantum optics and metrology. The ultimate goal is to enable ring laser observations as a complement to classic space-geodetic methods towards more precise, high-rate estimation of Earth Orientation Parameters (EOP). Furthermore, we plan to develop (trans-) portable ring lasers fit for weak, broadband 6 degree-of-freedom ground motion observations towards better understanding of atmosphere-solid Earth coupling (also relevant for seismic decoupling of gravitational wave detection facilities).

The project offers postdoctoral and PhD topics in laser physics, geodesy, geophysics, hydrology, and seismology. The successful candidates will be part of a multi-disciplinary research team at various institutions in Germany with excellent training and experimental facilities.
